Query: Disappointing

Too bad.The swim mask looks cool, and we succesfully got the batteries into one side. That side lights up. The other side -- the screws stripped immediately, so the cover plate can not be removed, and batteries can not be inserted.So we tried it with only one side lit, and on the first use, the strap split apart. Toy is unusable. I retrieved the batteries from the first side and tossed the toy.Not recommended.
