Very fun toy, but there is potential to loose a key component, so be careful where you play with it.
My kids love playing with their toy battlebots. They play with them several times a week and have held up well. The only thing I would say about tombstone is that we had an issue with the spinner. This is why I reduced the quality rating. The spinner has a central shaft that held in position by shaft with some threading at the end with a tiny nut. At some point the nut came off and we lost it. I contacted hexbug and they sent me a replacement at no cost. I took the bot back into the pit and was able to get it back up and running. Great customer service from hexbug.
