I bought these for my grandson for his birthday. I wisely decided to test them out before sending and I am glad I did. No sound out of one of the speakers and the jets of water stopped working from the other after a short time. Sent them back.
I bought this on the understanding that it would work with Win 7. Well after my laptop rejected it and asked for drivers, I went off to Sandisk support for what I thought would be a straightforward download. Not so. I have been waiting over a week for a satisfactory solution from Sandisk and they just don't seem be able to help. My friend has now also tried on her system with similar results so I know it is not my system. I have now had enough and am going to send it back. It should really say that it is not compatible with Windows 7.
