I'd like to purchase a Wireless Cycle Computer that measures Cadence.

I've short-listed a few computers, and I wanted to ask the Forum for their advice/own experiences.

I expect that the usability of each will be similar?

Specialized Speedzone Sport Wireless Cadence Computer
£29.99 ($47.20 US)

Cannondale IQ400 Dual Wireless 18 Function w/ Cadence
£40.00 ($63 US)

Velomann V.1.16C Speedstar 16 Function Wireless Cycle Computer Cadence
£44.99 ($70.80 US)

BC1609 STS Wireless Cycle Computer
£47.50 ($74.80 US)


Thank you for any help!
