someone used the wintech computer?
is it good?

I've put about 500 miles on one in the last two weeks. Works good so far but I have not encountered any rain yet. The tie straps for the wireless cadence are flimsy, already broke one, but no big deal, just keep some spare tie straps with you. The front sensor is a little larger than I expected, but it has worked well so far. The magnet sensor for the front wheel needed a little modification for bladed spoke mounting. The cadence magnet fits in the spindle hole of your cranks. I had to use some silicone to get it to stay on my cranks, my cranks are carbon so I'm not sure if that had any affect.
