BARTUN Bluetooth Wireless Tire Pressure Monitoring System with 4 Extemal Sensors, Real-time Displays 4 Tires' Pressure and Temperature TPMS, Supports Android and iOS (1.5~92.8Psi/0.1~6.4Bar)

Cost money to buy this junk. I thought it would alert me when it goes below 25psi (original at 42psi pressure filled) but didn’t do anything. When I checked my tire pressure with a real pressure meter and the reading was 16psi. It’s very dangerous to ride a motorcycle at a very low pressure. Stay away.

They weight of the valve stem pieces caused my valve stem to tear and loose all my tire pressure and destroyed my brand new Metzler tire 300.00 tire is now garbage and have to replace it again my advice to anyone thinking about put these on your tire don't do it or you could be replacing a tire like I am now

Unfortunately....Reads are incorrect. Throws warnings about low pressure after tyres sit in the California sun for a while. Data pull rate is on the slower side. Took 20-30 mins just to update the values.

Accurate, easy to use, will design, etc. Just a soild product that gives the peace of mind of knowing the current PSI and temp of the tires on your vehicle. Recommend!

I purchased this for my travel trailer tire, the valve is very secure with lock but. Excellent product, i will buy more

It will save your life

Easy install and simple operation

Easy to read,works well so far. I no longer need to constantly check tire pressure to insure the maintenance of the tires and my own safety.

So, I drove 300 kms with 2 leaking tires, according to the tire minders. However, during that 300kms of leaking, the tires did not lose any air, none, nada, zero.Coming back, same thing.So.... do they work? Don't know but they do send a signal of some kind.

I had to resync several times, and they're now junk because I lost the box which contained the sticker with the barcodes for syncing.

Just junk. Feel apart in my hands. Save your money and buy something decent

Item fails to read Data most of the time, I have to restart the app many times to get the accurate reading!!!
