Got one because it was cheap, fit alright and it was all the local bike shop had. And my V2 was in about 4 pieces.

Nearly bought a jusstissimawhatsit one, but it was £50 more and only in blue.

Convenient, but noisier than the caberg V2, and a little draughty.
The only annoying thing is the vision at bottom outer corners is slightly more restricted than normal lid, so you've gotta move your head further to check shoulder. Might be more noticeable because my nearside mirror is in 2 million pieces, and a sore neck.

I'll reserve judgment on this one untill I've had it a while longer...
