Based on ??????????? Not being funny, just never seen them other than I read someone had bought one back from the states.. China to USA to GB, none too green.
Bought a spotting scope for my grandson, when it came it was falling to bits, there was actually a hex nut rattling about inside, I got my money back no quibbles as if it was the norm, I read somewhere that if you want a good one you have to buy 5 and you might get lucky.
