I have one too. Having the sensor built into the skewer is a very good alternative to having an ugly fork mounted sensor that is prone to slippage. I mount my computer on my aerobar too.
As good as it is, I have a couple of comments about the unit:
1. I wish the computer were a little more compact. It's a bit bulky.
2. The buttons can sometimes stick. It may be due to sports drink spilling on it. I've tried to rinse it, but I've found that occassionally spraying a little WD-40 is more effective, although I don't know if its good for the rubber.
