The original clear M-tank for my R91 (authentic) would not tighten without the threads stripping, so I got 2 of these and they're both doing the same thing: when you tighten (screw it in) it the threads strip and do not hold.
Where can I get a good replacement tank for the R91? Never had this problem with my Kayfun Lites.
