Battery on the display lasts months without sun. Solar is a nice bonus.
Installed in 5 minutes, no shop needed. Reads accurate vs my pencil gauge. Solar charging means I never plug it in.
Sensors are tiny, no balance issues on the wheels. Set-and-forget.
Saved me from a blowout at highway speed when a temperature alarm went off — pulled over and found a bulge.
Picked up a slow leak on the front passenger tyre on the way to work — would've been a flat by lunchtime without this.
Alarm is loud enough to hear over the radio. App could be better but the unit itself is great.
Display is clear in direct sun. Good design.
Honestly didn't think a $50 TPMS would be this good. Surprised.
Caravan mod for me. Pressure visible all the time without getting out — peace of mind.
Took 5 min to install the sensors. Wife's car got the kit, my ute is next.
