Its been now almost 2 months that i've reveived a broken T2 red dot.
Tried to contact 6mm but that took a week alone. They responded that they will find a solution in 48 hours.. One week later still no message back, so i once again asked them. They replied with the same message.. - 48 hours bla bla -. After a week again nothing.

Tried to contact them 2 times more but similar reactions.
They offered half my money back which is ridiculous.

Untill this day the issue is not solved and they dont seem willing to find one.
