VESAFE Universal Solar TPMS, Wireless Tire Pressure Monitoring System with 4 DIY External Cap Sensors(0-6Bar/0-87Psi), Real-time Display 4 Tires' Pressure and Temperautre. (Gray Display)

My original review was based on my experience reading the instructions and installing the system. My comments were noticed by the seller and the seller contacted me about my concerns. They responded very quickly and I think the instructions are now much more helpful. Kudos on the quick response.When I first put the Display unit on my dashboard, I was concerned that the Anti-skid pad might not hold it in place. After testing it on a variety of roads, ranging from interstate highways to winding mountain roads, I can say that the Anti-skid pad has worked very well. The Display unit did not move around at all.When driving, I have observed the pressure and temperature changes that the instructions say to expect, so I know that the sensors and receiver are working. I have not had any experience with the alarms, and I hope I never do, but given my experience with the unit so far, I anticipate that they will work as advertised.Based on the fast response from the seller and my additional experience with the unit, I have raised by rating from 3 stars to 5 stars.I have recently purchased and installed the VESAFE® Tire Pressure Monitoring System. As of the time I am writing this review, I have had it on my car for less than one day, so my review will focus on the instuctions that came with the unit and my experience with the installation process. I plan to update this review at a later date.A. The instruction booklet. There are 3 general problems, 1. information is missing 2. information is written in the wrong order and 3. information is just wrong and/or confusing.I will start with missing information. The first piece of information that is missing is how to turn the unit on and off. By trial and error I learned that you do it by lightly pressing and holding the On/Off button for about 3 seconds, but it would be nice to have that information in the instructions. The second missing piece is: Check and adjust tire pressure before installing the sensors. If you don’t, you may have to remove the sensors and the security hex nuts, adjust the tire pressure and then reinstall the sensors and the security hex nuts. The third missing piece is the location of the “—“ (minus) button. You will need to find it to adjust Parameter Settings. The figure shown is the first of a series of figures in the instruction booklet. The buttons are labeled On/Off, “SET” and “+”, but the “—“ button is not labeled. The On/Off button is also the “—“ button. It is possible to accidentally turn the Display off while setting or adjusting parameters. The fourth missing piece is the “Standby Mode”. The instructions in the “Sensor Re-coding” section refer to the “Standby Mode”, “1. In standby mode press …” and “5. … or return to Standby Mode …”, but there are no instructions about how to get the unit into “Standby Mode” or how the Display would let you know that it is in Standby Mode. As of this writing, I think standby mode means turn the Display unit power on, but I am not certain of that. The fifth and sixth missing pieces were found on the VESAFE website. Below are the instructions from the Instruction booklet on sensor installation:Sensor Installation:1 Fix the hex nut in the valve2 Fasten sensor to the tire valve3 Use the special wrench to tight hex nuts in counter clockwise direction.Information from the website:Tips for Sensors Installation1. Be gentle to the valve stem when screwing the sensors. It’s best to pinch the valve stem with one hand and then screw sensors with the other hand.2. Turn on the monitor first before installing the sensors so that the monitor can receive the sensor data on time.3. Ensure no air leakage over after installed and may use soapy water for testing if necessary.Now, information that is in the wrong order.Display Installation: First, “Place the display appropriately … with the anti-skid pad.”Second, “Please have the display fully charged by [using the] charging adapter for the first time using …”You may find it easier to charge the display unit before installing it; charging mine took over an hour.Information that is just wrong and/or confusing (I used ALL CAPS to emphasize the problems):“Parameter Setting: …5. High Pressure Setting for REAR TIRESWhile the two FRONT TIRE ICONS and the low pressure data icons are flashing, press the button “+” or “—“ to select the desired data.6. Low Pressure Setting for Rear TiresWhile the FOUR REAR TIRE ICONS and the low pressure data icons are flashing, press the button “+” or “—“ to select the desired data.”There are also instructions for high and low pressure settings for the spare tire which is confusing because the kit contains only 4 sensors.B. The installation process was fairly simple after I found the missing information. The small wrench for the security hex nuts that came in the box was awkward to use. I found it faster and easier to hand-tighten the nut against the sensor and to use the wrench only for the last bit of tightening. The security hex nuts got in the way of my tire pressure guage, so I had to remove them to get accurate pressure readings.C. Other information. The Installation booklet has the following information on accuracy of readings.“FAQ:1.Q: Is the pressure and temperature reading accurate? A: The unit is developed with the latest technology which makes the unit reliable and provides accurate pressure readings.”The answer to the above question only addressed accuracy of pressure readings and said nothing about the accuracy of temperature readings.As for the accuracy of the pressure readings, I set my tire pressures to 29 PSI in each tire using a digital pressure guage and a mechanical dial guage. The VESAFE Display showed 28 PSI in each tire. So I now know that, at least for my sensors, 28 = 29. Because of this discrepancy, I reset the Low Pressure warning for my tires by one PSI.Update note: On the box the unit came in, it says "Accurate readings ± 1 PSI".

Great little unit and easy to use. Lasted just over a year and now won't take a charge. Only works when it's plugged in.Looking at doing a battery replacement cause i like the unitUpdate... Found new battery with higher mwh rating and replaced it.. Problem was it had a different connector so i salvaged the old connector and rresoldered it to the new battery.. Fixed.. But for how long?

Already has two in previous version in my and my wife cars.If you have few sets of wheel & tire better to have this device, original sensor costs same price as this system and required re-programming after winter/ summer wheels changing.Bought again due to one sensor was stolen from my wife car.Before spare sensor was available at Amazon, but now discontinued, it's a pity. I had one spare but was replaced due to sensor destroyed by road stone.In my FJ Cruiser original TPMS disconnected due to I have three sets of tires and wheels, so this device is perfect.

Don’t get me wrong, this product is easy to use, accurate within 2psi and 5 degrees. However, after the purchase, I realized it is not designed for heavier vehicles such as even a small 22’ RV, the reason I purchased the product. I had to upgrade. I guess if you wanna monitor you lawn tractor tire pressure, this can do the job.

easy to install, super fast to program very friendly, gave it four stars because its off two to three pounds of air, one thing i like is that it turns red when a tire is of the set pressures and it beeps which is cool, over all after three months good battery and solar recharge, still working.

I have tried several budget TPMS add on sensor systems on both cars and motorcycles, and the Vesafe brand just works better, and responds more quickly than the others. Plus, their customer service actually responds to inquiries! I have had other budget brands that failed out of the box, either one, or all sensors. This model worked right out of the gate. It was easy to setup. Just turn the device on, and replace the stem caps with the included sensors. That's it! I found their default warning settings to be more than adequate, so no adjustment was required. This is a solid unit for a good price!

I have decided I really like knowing what the actual tire pressure (and temp) is. Yes, my car has one of those built-in TPMS setups, but that's kind of like having an idiot light for knowing whether the oil pressure is good or not. I bought some of these a while ago and the display on those wasn't as good as this new model, and I like the changes they made. I have learned to just plug the receiver in all the time rather than relying on the solar charger and batteries. If you park your car outside all the time then this likely won't be an issue. With the pandemic and my garage I had issues with that aspect, but I don't blame the product for that issue. No sun = no charge :-)

To get a TPMS on my vehicle from factory would have required the next trim model which would have been over $5000, so getting this device was really worth it. Always be aware of your tire pressure at a glance. I’ve had to charge this a couple of times because during winter there wasn’t enough sunlight to keep it charged. The batteries didn’t last as long as I had expected (less than a year) luckily I was able to find a store that sells the batteries for cheap, so a small addition cost to pay for having piece of mind.Update June 5, 2019 - so it’s been a bit over 2 years and the rechargeable battery in the main unit will no longer hold a charge. Unless I plan to keep the unit plugged in all the time in the van, this unit is basically useless now. I suppose for it to have lasted this long was pretty good and I noticed the price is actually $40 less than when I originally bought it! Not sure if there is anyway to replace the rechargeable battery, but somehow I don’t think there is.Even though this unit never let me down, I am going to try another brand and see how that goes.

Excellent product.Seems to be very accurate even in winter months. It has been so cold that starting out in the morning has set off the alarm due to the tire temperature being too low, however after a couple minutes driving the alarm went away.Great way to ensure your tire temperatures are not too low or too high. Instructions are good and parts are well labeled.Would recommend to anyone who doesn't have factory TPMS and wants a low cost work around.

Handy while they work. Have had many problems with them though.Battery lasted one year.Irregular battery size. Haven't been able to find a replacement.Anti theft lock will rust shut, making it impossible to take off and damage valve stem. Recommend not using the anti theft ring.In cold weather valves will freeze open. You can't take them off to pump your tires or get a reading without losing a ton of air.

I've had this setup since November of last year and all was good until we had a long stretch of overcast weather. The batteries drained so I plugged the unit into a usb charger and it didn't work. I've tried multiple chargers and even more cables and none of them work. These chargers and cables all work with other items so I know they are not the problem. Let's hope the sun keeps shining so I can keep this thing working.

PERSONALLY I found the "setting up" instructions a bit complicated. They refer to "+" and "-" , and "set" keys, but none are designated on the device. A lot of steps to key in minimums/maximums. In the end I just left the factory presets on it. My concern is to know individual tire pressure, especially on long trips, and using the presets gives me adequate information.

Unit itself works great. Easy to install. Reads within half a psi of what my digital pressure gauge reads. Only problem is the sticky pad doesn't stick to my dash. The auto shutoff after 10 or 15 minutes of not moving is nice and the unit turns itself back on when you hit about 30 to 40 km per hour.
