Convenient because the set pieces automatically rises by lifting the lid. We immediately know how the sums are different rooms, the numbers are very readable, large enough. I regret that we could not raise the cash compartment to slide checks below, but for the price it is a practical item, which looks solid. We must remove the key after closing and ensure that the cover is closed, otherwise the key tends to go down and if you carry the box with the handle on top, the lid opens and there is a disaster because everything is down! but if you take this precaution there is no problem and the pieces stay in place. Good buy. It is big enough!
