Almost perfect
Okay - I have two wishes1) A better way to 'lock' it to the valve. The 'jam nuts' supplied (a) get in the way if filling tire after sensor removed and (b) don't thread far enough down the stem unless your stem has pristine threads. It also means removing both the jam nut and the sensor with the supplied wrench if you ever need to 'top off' the pressure in your tires.2) Rocboc was kind enough to supply two spare sensor batteries, why not 4? If a sensor battery dies after a year or so - I would replace all 4 at the same time.Now for the PRAISE!1. Although the instructions are in poor English - they are THOROUGH instructions if one reads them carefully2. Tremendous bang for the buck. Far exceeded my expectations3. Display lets you know when the solar cell is charging the control panel4. Display lets you know if any sensor battery is getting low (or has quit) and gives you plenty of warning5. Changing the CR1632, one for each sensor, is relatively cheap and easy to do6. It appears that there are actual 'O'ring seals for each sensor cover!7. Swapping sensors, or replacing a sensor is supported. The Menu allows any compatible sensor to be "paired" with any of the tire positions on the display.8. Reporting the tire Temperature is nice9. Setting both HIGH and LOW limits is wonderful. You can set limits for both Temp and Pressure. The pressure limits set Both Front as a pair, and both Rear as a pair10. allowing for Bar or psi, C or F to be displayed is great!11. the solar cell seems to be "ruggedized", with a thick clear coating of some sort which I believe will prevent cracking if struck or damage from moisture or fumes. (One small gripe: My solar cell came unmounted by itself when I turned the unit over. I carefully put dabs of contact cement between it and the case because sitting on my dash in the sun, or in the cold of winter, hot glue would obviously fail).12. the control unit shuts itself off after a couple of minutes, and restarts when you open the car door or otherwise cause vibration of the unit - as advertised!13. The internal battery in the receiver-display unit was still showing "FULL" charge, even after I played around with the system for a full 40 minutes without any USB or solar charging!14. The display flashes 1, 2, 3 little squares inside the battery symbol when USB charging, just like all my other USB chargeable devices with displays. Very chic.All in all a very sophisticated little system. They've thought of everything.The female voice is pleasant, if a bit tinny sounding due to the very small size of the speaker. The volume might be too low to hear well in an older noisy car or in a car with a loud radio.I will brush a dab of varnish on my valve stems - after the sensors are installed snugly, to 'lock' the sensor to the stem as I won't be using the supplied 'jam nuts'. The varnish should prevent the sensors from un-screwing themselves while driving, yet should break away easily if I need to fill a tire. Then I'd put that sensor in my glove box until getting home where I could 're-glue' it to the stem with varnish after re-installing it and checking that it's working okay.I will order another one of these systems for my son who's car is not new enough to have built-in TPMS.

Small, Does Not Obstruct View, and Useful
First impression of this product is that it is a lot smaller that what I expected and that it works great as an auxiliary monitor to the ones already in my car. I’ve tried a couple of places to place this(attached photo, for your reference) and it really doesn’t block you view of the road at all. The installation and setting was easy, though it does take a while for me to understand the instruction, but you pretty much just have to screw the sensors on to the tire. The hub itself is solar powered so you don’t need any kind of wiring, which is the best part imo😂This product is good so far, and I’ll update if anything else comes up.

Two of our three have had problems
The first set I ordered caused a leak in one of my tires. I sent it back for a replacement set. That set appears to be working. I ordered a set for my other car. It was working fine for a while but now one of my tires is leaking air. I realize now it's because one of the sensors lost its seal. I am now out of my return window unfortunately because I realized the problem too late. Overall, I'd say it has the potential to be a great product but it's cheaply made. Therefore, I cannot recommend it.

very good
The media could not be loaded. very good and useful, easy to install. when i need to check, just switch it on. and you see one of my tires is in low pressure. its good

Garbage.
The media could not be loaded. How did it get so many positive reviews? First, the wrench is wrongly designed and made from very soft metal, very hard to use, bends easily. Second, the Front Left sensor is badly leaking. Not the thread but the sensor itself (see video). The other 3 sensors didn’t show any leaks but lost 1-3 psi overnight. Should I pump all wheels every day? Don't recommend this product to anyone.

not accurate, broke in a month
At first they were all point on, but after driving at the temps rose, they went wack, and even after cool down they were wrong. they read 31, 35, 39, 33, i checked them with a trusty guage and all were 34-35psi, after re installing and 3 weeks of use they just dont work right and always give completely wrong readings in psi and temp, emailed the contact info i got in the package... it was a dead email. i plan to return these. i dont get how they massed this up, i wanted to love it and was excited to use it.(the image is about as accurate as they get, they are ususaly worse, this was after a bit of driving, checked all pressures and they were all below 37 psi)Update: less than a month and the monitor no longer turns on.

It works but not sure if all sensors are calibrated the same.
Small and compact unit. Solar charging works well. Not all tires read the same when cold and inflated to the same pressure. Same for temp readings first thing in the morning when all tires should be at the same temp. Useful enough but I would prefer better agreement between wheel sensors as I primarily want it to monitor tires deflated to run on the beach. I worry that sensor to sensor variations of up to 2 psi and 5 degrees are more of an issue when running lower pressures.

easy to install
and good enough user interface
