Bought it knowing I have the wrong type (older style) stem, but was able to attach it to a bracket attached to the headset. It's lower than the bars but looks good & reports the temperature well.

Works great

I like the thermometer. I looks nice and so far has been reading the temps accurately.

It was nice, and worked well until I looked down one day, and it was gone. The thermometer popped out of it’s casing and is who-knows-where. The housing is still firmly attached though.

The mounting instructions were a bit unclear. I thought I needed a separate mounting piece for it to work, which it turned out I did not need. It is winter and the bike is in my basement so I don't know how well it works on the road, but so far it reads my basement temp accurately.
