Review: Works great! - Good cash box! It comes with the suggestion stationary and we needed that for what we were doing so that was a plus! It's sturdy metal and large. Works fine. Great for safer locations. Looks professional.
Review: Really good product, especially for the price - Love everything about this item. It is strong, from the material used to make it to the locking mechanism. I really like the magnetic sign sleeve. We probably won't use the printed suggestion sheets that came with the box, but other than that it is exactly what I wanted. The only slightly negative thing I would say is if you are looking for a box you can secure to a wall you may want to look a little more. This one only has two holes in the back to hang on a couple of screws and I do not think it would be difficult to get off the wall if someone wanted to do so. For my purposes it doesn't matter. Also, for the price, I feel like I got a high quality item that looks really nice.
