Removable Bracket & Pressure Accuracy 0.01Bar

This product is perfect for me and my needs. I had a blowout due to low tire pressure and that freaked me out so I purchased this. Just in case I had any more tire pressure problems I would know immediately. It seems like it automatically calibrated and I get a notification beep when the tire pressure gets below 29 psi. It has helped me out so much and I would purchase this again and again for other vehicles also the solar powered charger is a plus as well. I love it I don't even have to plug it up into my charger at first I was skeptical about that but it works amazingly and I haven't used the charger in a couple months. Update: one's drawback about this device is one of the tire pressure sensors is delayed in reporting the tire pressure. I don't know if the battery is going dead or what but I don't even know what size batteries this device uses I thought I had the right size but those were too big. So now I'm on a man huh for the correct battery size for this product. But like I said I don't know if it is actually a delay because of the battery or if it's a delay because of the product being defective. It's like I'll be driving for about 15-20 minutes and then it'll start beeping showing me that the tire pressure is low so if that would prompt me to check my tire pressure before I leave the house. And make sure that they are correct by using my tire pressure gauge.

I was really excited to buy this and installed it on my 2013 Hyundai Santa Fe. It is unsightly to see but that seems like a small price to pay. The screen adhesive sucks and it constantly falls into the floor daily. The worst thing is a week into using it one of the sensors stopped transmitting any PSI info to the screen and worse allowed the tire to leak it's air out til totally flat. I'm positive nothing is wrong with the tire. I tested this by refilling the air, then swapping the sensor in question with another sensor. When switched now the alternate tire was displaying 0 PSI and within an hour the tire was completely flat too. Very very disappointed and wish they'd send me one replacement sensor

I bought another model from Jansite and had it for several years and it worked fine. One of the external sensors got damaged by a curb and I enquired about getting a replacement, but no one from Jansite ever responded and I couldn't find them selling replacement sensors. So I decided to by this upgrade version which installed smoothly and was working fine until I got a new set of tires. I took the sensors off before taking my car to the store to get the new tires installed. With the new tires on the car, I re-installed the sensors on the tires. They read the pressure and temperature, however, the unit beeps and the readout blinks rapidly every time I get into the car. I went through the manual attempting to re-set the unit according to the instructions but nothing changed. I sent an email to their support email address over a month ago and like the last inquiry I had - I have heard absolutely NOTHING from them. Not even an acknowledgement that they received my email. Meanwhile I can't get rid of the annoying beeping blinking and the display flashing. CAN SOMEONE FROM THE COMPANY PLEASE TELL ME HOW TO REMEDY THIS CONDITION WITH THE BEEPING AND BLINKING LIGHTS? I'm happy to update my review if someone contacts me to solve this problem.

**Update** The seller reached out to state that this model "only supports small cars, pickups, and SUVs, and the maximum tire pressure is 87PSI. Medium and large cars, trucks, vans, trailers are not supported. Usually, if the normal working distance exceeds 19.8ft, it will not work normally and abnormalities may occur." They are working on a newer version with a repeater that should resolve most of my concerns. They have also updated their videos and the double sided tape. 5 stars for their efforts to satisfy the customer! I bought this for use on my car trailer. I've since returned it. The only pros are the solar charging and it is very clear to view. On the other hand, it constantly fell off the windshield, never really tightened up to the holder, always read about 20psi less and the temperature feature was wildly inaccurate (reading outside air temp rather than tire air temp). The only thing that this really excels at is a complete tire blowout. If/when that happens the pressure drops and the alarm sounds. Honestly though, you'd probably know that you had a failure without this anyway which is why it was returned.

Initially worked great, but then the temperature functions stopped working

I've installed these on our road trip car, and they seem to work fine (measurement looked reasonably accurate, within 1 PSI of what I expected). But we haven't taken a road trip yet (I'll update here if anything changes after that first road trip). Installation was simple, although I couldn't use the included hex wrench tool because of tight quarters in the wheel+cover (I might have been able to use it if I'd removed the wheel covers, but I didn't do that). Tightening the hex nuts by hand seemed fine to me. [Update] We've taken our first roadtrip (about 10 hours round trip). 3 out of 4 worked great :) But the Front Right gauge never changed from the initial numbers it showed. It appears to be connected, and the monitor starts beeping if I remove it (like it's lost pressure), but the gauge doesn't actually update for some reason. It's entirely possible I've put it into some kind of "hold" mode (if that's a thing). I'll update this again once I get some kind of fix (or a replacement cap).

I have two of the previous generation TPMS monitors from Jansite. They work well aside from the occasional false alarm. I figured the next generation of this product might get rid of the false alarms, and I think it may have. They also added a clock feature to the middle of the display, which is nice on vehicles that don't have a clock... The previous version does a great job of managing the brightness of the display for day/night viewing. This version does not. The display is fairly dim at all times, and putting the unit in the sun turns on the "sunny" icon, but the display gets almost no brighter at all. It is fairly unreadable during the daytime. Even at night, the display fades from right to left, such that the right side is fairly reasonable, but the left is pretty dim. I still think the temperatures are stupid. They mean just about nothing with external sensors, and they could easily go away and not be missed by 99% of users. Then the display could be smaller, as with the earlier version, which tucks in above the rear view better than this "updated" version. Kudos for solving the false alarms but total fail on the new display... My $0.02: Buy the old version, it is better in most respects.

My tires always relay a sensor error for pressure on my dash. I've had this tpms for a little over 2 years and it just now stopped working. I only had to change the batteries in the caps twice and it usually stayed charged by solar power, except when it spent extended periods of time in the garage. Rarely did I have to charge it using a cable. I'm not sure how much I paid but it was under $40USD. I would buy it again.
