from my experiance here at rares the locks are very hit and miss depending on the batch, these are all bought in and as far as im aware are all the same brand no mater where you buy them, they arnt a rares product we just sell them.

we are attempting to remake alot of the locks in a much better quality then whats available currently

if you buy a repro lock and its still good after one day they are generally great for life but some tend to lock up and wont move from its parked position which i generally check by turning it a fair few times as the customers buying them over the counter and seeing how they feel, ive had 1 customer that had 3 fail in the space of 3 days then the 4th has been going fine for the last year etc

hopefully we get the new repros soon to avoid any potential issues
