Underwater camera housing Nikon?

I want to buy cheap underwater housing for my Nikon S3500. I have seen them cheap 'Bingo' cases on eBay, are they any good?
I have also seen a cheap multi-use one 'B Square Underwater Camera' on ebay. Is this any good?
I don't want to spend a lot, and all I want is good clear photos, I'm a professional just want to take good holiday snaps while scub diving and the like.

Hi cheap anything is never a good idea. Has no one ever told you that fact.
