Summary:
This cyclocomputer has an intimidating number of features, but for basic use, it's very simple. Just hit one button several times to clear out your current ride data, then go.

Nice big buttons on the top let you switch between cadence, ride time, average speed, etc, and it always shows your current speed. The display is very clear and the numbers are large enough to be easy to read.

Unlike several devices I was looking at when I bought it, the optional cadence sensor is also wireless. Not having to route wires to anything is a major advantage.

I have had two problems with my C4. The plastic housing on the first one I had cracked (Performance replaced it under warranty), and the cadence magnet fell out of the plastic holder. If it weren't for those issues this would be a five-star review.

The VDO C3 DS is basically identical except it lacks the countdown/interval timers. If you don't need those, it's a better value.

Strengths:
Easy to use
Easy to read
Wireless

Weaknesses:
Cadence Magnet attachment
Durability
