Yeh ive spoken to a bloke who really knows what hes talking about and he strongly recomends bauman (not sure how its spealt) he recons they are better than 'snap on' but they arent cheap, they are sposed to bend 20degrees before breaking! not that breaking allen keys will neccecarrily be a problem with a paintball gun lol.
although the quality far outweighs the increase in cost im worried people wont be willing to pay for it.
Also you are sure that it was an unbrako key? because as far as im aware alot of people refer to any ball ended key as unbrako.
