I've been pretty happy thus far with my 1000, took a little bit to figure out but I've used it on multiple bikes now (w/old and new sensors) without issue. The text/call display feature is nice as I used to have to really pay attention to my phone while riding (jersey pocket etc.) and stop for every one if i was waiting for a time sensitive call, this feature gives me the freedom to pick and choose which calls/text need my immediate attention without stopping the ride. I also noticed they didn't initially fit in the old K-Edge mounts, this was easily rectified in about 2 minute with a sharp file
