You wont find many reviews due to theres less than 50 in first batch worldwide, might be less.
The future ones look promising with ret on glass.
True there are a lot of BSA around, since came to the market i have only ever seen 3 good ones in well over hundred. Same with earlier Nikos, just a rebadge and had both, the BSA for an hour. We wont go in to the return rate and were labelled the disposable scope.
