Aqua Control + or MP510

Basically just the title. After some research I’ve narrowed down my considerations to these two pads, I was hoping someone might have experience with both and could maybe tell me some about the differences.

I’ve also seen some horror stories ab MP510 in my searching but also many love stories, if you haveeither please share.

Finally if anyone knows a rough shipping time for xraypad to NY the knowledge would be appreciated.

Thanks for any help in advance.
