I bought a $30 knock box of similar design on amazon, and the silicon gasket around the top edge quickly ripped. Then I got this cafelat one, and it’s clearly higher quality. Worth the money, as I expect this one to last much much longer. Buy once, cry once.
I also love the huge rectangular shape. It fits a lot of pucks and is the same width as most of the larger round knock boxes, so it doesn’t take up any more space in practicality.
The only downside is that the bar is fairly hard rubber and thus is louder when you knock it. But I noticed that pucks do come out easier and cleaner because the bar doesn’t deaden the impact.
