Review on Sumnacon Cylindrical Bumper Safety Commercial Industrial Home Decor by Erin Brown

The washers themselves are fine. They're a lot smaller than I thought they would be, but they're nice, heavy, and seem well made. The negative feedback is because the included screws are very cheap. And they're extremely hard to find in the US. We bought 9 of these for all our exterior doors last fall and so far 3 bolts have bent or broken from the wind pushing the door against the doorstops. I have contacted the seller to no avail. The bolts are M8 stainless steel anchor sleeves for concrete. So far the only online shop I can find that charges significantly more money for the bolt than I paid for the doorstop 😔
