Only the people who love or hate a product typically post reviews. When it's something as inexpensive relative to all the other things bike, only those who hate it are likely to post.

What features are important to you?

I'm prone to simplicity so I use the old Cateye Enduro and Mity 8's. I tend to ignore them after settling into a good rhythm at a comfortable speed but I do watch distance on the mountain bike. I don't want to miss my route cues.

My only bad experiences with cycling computers relates to malfunctioning in the rain (duh!) and Shimano Flight Deck road bike mounting brackets that don't seem to work with detachable faceplates.
