I just returned from a week's touring in eastern OR, an area with LOTS of hills. Installed this device shortly before leaving. While the device can be adjusted on the fly to make sure that it registers 0 deg (flat) when you're on a flat as the benchmark, it would often tell me I'm going up when I'm going down or down when going up. There was little consistency it its readings. Which means it adds nothing to what I already know. Not much harm in having it on the bike; it is light and easily removed. But also of no real utility.
