I used them twice last year and their service was terrible both times. I wont use them again unless no other alternative.

To be fair they were pretty good with me, I had ordered an O2 optimiser and then later decided for the PCV, they matched the price of the combined deal they had even though I ordered separately and then when I had issues with my O2 optimiser not long after (Speedo wasnt stable after installing, jumped around at steady speeds etc) they accepted a return no problems.
I would use them again if I needed something else.
Kevs O2 mod sorted the speedo problem thankfully :occasion14:
