Hi Everyone, thanks a lot for all the comments!

I think im gunna get my hands on some of the manutech ones and give them ago. Good to see im not the only person who liked the fit of the hotbodies ones (although i havent broken one yet, touch wood... actually maybe hope not to touch the wood).

BTW i did actually look at HBOnline because they had some kind of moving sale unfortunately they dont even list the part im looking for, those are the old ride height adjusters which only come in 1mm increments
