Wanted: Freewheel 22T for £10

got myself a 20t ACS freewheel from ebay, which sounds similar to a WI, and with a similar appearence. it's 3/32 as well so can keep my original chain!
Dunno about the freeman cycles one but I think this is sensible advice against getting it :

watch out with the really cheap ones, they can be really hard to get off because some have no groove for a removal tool. You have to literally destroy them to take them off.
