Query: Neither one worked.

WARNING>>>I bought two of these for my Grandkids, neither one worked. I've bought plenty from Amazon, but never had to return something. I read the return policy and that was a ripe off too. If the product has a defect or you find out it's an inferior product and you want to return it then you have to pay for the return shipping. After knowing this I took them apart to see what was wrong. One had no attempt to solder one of the joints. The other unit trigger finger was so wobbly it would not allow the intended function to work, I maight be able to salvage one out the two, but I'm not paying return postage for both and getting nothing in return. So Amazon has a few things to learn. There is no way to contact them, they are too big.
