This knockbox is great when you need an on the counter box and don't have a lot of counter space. The built in backsplash saves a lot of counter/wall cleanup. The rubber base works great to limit sliding. The only problem I've had is the bar itself. Because it does not lock in place and the rubber wrapping is too thin, we went through our first bar in 3 weeks (at a pretty busy shop). But I replaced this bar with one like is used in the Rattleware knockboxes and it has solved the problem and provided us with a great countertop box.
