I went way out of my way to get this product for my son.
He's played with it twice. It is very difficult to get it to work.
I put brand new batteries in the tank and remote and messed around with it for five minutes. I got it to work for five seconds.
It's a neat concept, and my son would love it if it worked. It's a sore subject now. He keeps asking me to change the batteries so that it will work. New batteries don't help.
I think it cost me about $1 per second it has worked. My son hasn't been able to play with it long enough to have any fun with it.
The Tank looks brand new with no corrosion from batteries, but doesn't work.
