It wasn't worth the money. Obviously everything needs a battery but there were a few items that came with small (dead) batteries that were more expensive but they didn't work even when replaced. Laser Sentence: Only two of the three worked. There, two single lasers worked, but the dual lasers didn't work. Given the orders for the shelter, I wasn't able to buy all the batteries I needed. Now I'm a day past the return policy and I really want to return everything and get my money back! Worst of all, my kid who loves spy stuff is very disappointed.
