I had thought this would arrive ready to use, but that was not the case. First, I needed to buy 2 AAA batteries. It would have been nice if the advertising had mentioned: "Requires 2 AAA batteries, NOT included". Then I needed to figure out how to open the battery compartment. NONE of my Phillips head screwdrivers fit, so I bought a screwdriver set that contained sizes 000, 00, 0 & 1. One of them fit, not sure which one. When I put my 1st coin in, I was surprised that it did not go in easily & it double counted it. Now that I got the hang of it, I must confess, I'm enjoying it. I guess is was worth it. But I would have given it 5 stars if I hadn't had to spend an hour shopping for the accessories necessary to get it to work!
I really like this puzzle it's great for learning numbers, I only wish it was a sound puzzle, the sound puzzles are the best, at least they are for my son, he absolutely loves puzzles and is learning about things much faster than if i were to just teach him it.
