Review on Discover the Game-Changing Broadfix Revolutionary Flat Shims (1, 60)! by Craig Shah

If you stop reading and take nothing away from this, you know that. These washers are not accurate. They can still be useful if they're consistent, but that's not even the case. There is absolutely no quality control in their production. I bought these for use in woodworking where precision is important. Wanted to check they were accurate after realizing they weren't a solid piece but had a skeletal structure (last pic I uploaded). None of the spacers met the specified thickness in metric or imperial units. I thought, okay, maybe they're not accurate, but if they're consistent, they can still be useful. I took 4 colors of each of the 3 smallest colors and measured them in metric units and found that only between these 4 is there a +/- 0.1mm variance from the stated thickness meaning one of these at 0, 2 mm was more than the other is too much. I decided not to continue the test after realizing that I had already received the necessary information. mm1/8"3mm----7/64"2.88 m5/32"4mm----19/128"3.94mm3/16"5mm----25/128" 4.93mm1/4" 6mm - --- 29/128" 5.87mm
