Yup, I'm not massively experienced on the subject but I really like them, they're good in the wet.

On 33bhp, I've done 4k miles and theyre only just getting to the 1mm indicators (they're there as the tyres are guaranteed for 1k or 1mm of tread against punctures)
This is quite handy as theres a screw through the back one.

My local bike mechanic said that most people who have a set get the same again when they're worn out.
