Anyone tried them?
i've got the altitute one (can't remember the model number V1.20a, i think). Essentially pretty good, loads of info - all the usual stuff plus temperature, % gradient, altitude, total amount of climbing. Easy to use, good display. They can behave a bit oddly sometimes like today i nudged it on to the ride time and my current speed stayed at 50mph (which wasn't right!). Sometimes i don't trust the climbing data - once it said i was climbing a 70% gradient. But on the whole it usually works well and it is more interesting having different data and stats to look at.
Thanks for the feedback. You seem to get plenty of features in the price.
