I like it a lot more then I thought I would!

I have an older 80's trek steel frame and I was worried that it wouldn't work but installed the compass with a a few layers of electrical tape and small 1-2mm felt liner cut out stuffed in-between the compass base and my fork tube, no issues with magnetic interference (not sure the buffer is even needed since the compass sits above the fork tube in plastic cap, but per Cyclosource's disclaimer thought I would do it). Works great, very neat product!

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.
