BLE TPMS vc601 Bluetooth Sensor, Real-Time Temperature and Pressure Alarm Tire Pressure Monitoring System With 4 Internal Sensor (0-13.0 Bar/0-188 Psi) , Wireless Works For Andoid/iOS APP Display

My sensors didn't work but the instructions were not clear on the procedure to follow to verify correct operation. Maybe I should have known this beforehand or maybe this brand is not very good. But the process of mounting, checking, return, repeat is too expensive of a debug operation IMO. Next time I will be more educated although I thought I did a fair job this time researching the product. Just my $0.02.

The description says that it monitors pressures 0 to 188 psi. However the max alert pressure alarm setting in the app in 36.3psi. That will not work if you cold pressure setting is 110psi. Also the high pressure alarm is 92.8 according to the manufacture. Don't know how you are going to know that with the description provided! Anyway if this is a car and your pressures are around 32 to 35psi it may work fine but if your cold pressures on your tires are higher that that i doubt this will work. The app that they point too to use is the real problem. It uses sliders to adjust the alarm pressures and they max out a lot lower than you need for high pressure tires. What they should do is start with a cold pressure setting and then allow you to adjust the max alarm and max pressure. If those are within bounds of the hardware you are buying this may work just fine. If they did that then perhaps I would buy this again? But the apps the real problem for high pressure applications

I ordered these knowing there were many complaints that some sensors did not work. But I took a chance that maybe it was operator error. These sensors have to be "woken up", that is they have to have some movement, or rotational g-force to turn them on. So I mounted them one by one on an empty rim, and spun them on a tire machine. Even after varying the times, one as long as 15 min, not a single sensor woke up and registered on the Android app. So its either the sensors, or the App on my Samsung Galaxy 8+ phone with Bluetooth v4.61. Returning them to Amazon. Oh, I have two other sets, one stem mounted and another internal. They both wake up by simply shaking them. They are installed and working great. I was just hoping to be able to use my Android Head Unit instead of my phone or an extra box sitting on my dash.

Maybe try other productsI used these things! And honestly, they work intermittently, a sensor did not work. Got it replaced by the company right away😁. However, when I want to check the air pressure sometimes the top two work. Other times just one works, then none work! IDK what is going on. But whatever, I say stay away. A have a little bit of money to play with so for me it was whatever, if you are on a budget maybe save some money and buy good stuff

I really wanted this to work on my older car but one of the sensors did not work no matter what I try. So I return the item. Also the pop up message is in Chinese so is hard to find out what the message is.

Very unhappy with the instructions. Very unhappy with the app as it does not read the sensors, Very unhappy with sensors as they do not communicate with the app. I have a note 9 and this just does not work as a bluetooth TPMS system at all. I have all four sensors scanned into app, I have sensors installed in tires, I have the app from qr scanned card set as instructions. Nothing. Total waste of money and time, dont waste yours.

Great product one you get it installed by the tire shop

It will not sync up to my phone. The instructions are in chinese!

So far so good. Horrible instruction, the translation is painful to read. But had them on my truck a couple of days and they seem to work.
