wow, if this isn't an example of blatant product ripoff, i don't know what is. this is an almost exact copy of the original BLU TPMS i purchased some months ago.
regardless, i found out some disappointing info after purchasing the original version and using it on a trip. the tire pressure and temp only displays after the device has been in motion at 12 mph or more. in other words, you can't walk up to your bike, check the app for tire pressure and then make the decision to correct tire pressure or go on with your ride. to me, that's the whole point of a tire pressure check. do it BEFORE you ride. i don't want to find out AFTER i've left the house and my compressor that my tires need air. the system works great during a ride and after you've stopped from a ride. small consolation.
i have removed the devices from the tire schrader valves and gone back to using an old style gauge.
