Strengths: Simple instructions, no twenty languages to wade through. Easy, easy set up. Can mount on bar or most stems. Simple tri-mode display
Weaknesses: Stem Mounting bracket does not lend itself to mount on over-sized carbon fiber stems.
Double wireless, cadence and a minimum of other useless features. Is working for me with wheel manufacturer's little bitty weight and both transmitters in the non-drive side chain stay. Had to buy a different one because there is no flight deck for Dura Ace 7900, I really liked virtual cadence, when costing down hills, but als no more :-(
Strengths: The price is unbeatable for a cadence/wireless bike computer.
Has many fucntions
It's not huge.
Weaknesses: It has some down points though.
Like the display is somewhat annoying when it changes automatically to all the parameters.
Its sleep mode kicks in too early.
A little complicated to calibrate
This computer is the best you can get for 70 bucks in the market.
As a product it is very decent. No complaints.
