Works really well, simple to set up as simply plugged in unit to my Atoto S8 head (via a small usb hub as using the usb ports for other devices) - app was pre installed.

Watched a few you tube videos before ordering and looked a plug and play device. Not in my case. First thing I noticed was unlike in the videos, they are made of plastic and do not have a metal threaded base. As for installation, only one connected the other 3 said they were leaking. Admitidly I had not tightened the lock nuts because I thought they were more of a anti theft device than actually a requirement for giving an air tight fit. My previous tytepal device certainly didn't require this. Any way they are all working now but I am not filled with confidence. Will require monitoring carefully before I am happy... Or not.UpdateWell 2 weeks in and all are working fine.Really love the large display and the information it gives.

Bought it as a bundle with Atoto s8. Thought to give it a go.Very pleased. Some say that caps ar quite big, but the battery has to go somewhere so no issues for me. Also looks fine on 20 inch wheel.Gives alerts as well. In my case - can disable if I wish to via media unit.Are they precise? Hard to tell. Pump said 2.7 bars. TPMS says 2.95. Probably not overly accurate but certainly enough to feel safe.

I am loving this Atoto range. Everything I have bought and connected to far has worked brilliantly!
