I do not recommended using a water-based lube with these. My lube seemed to dry up from the friction when using this with my husband, and it became really uncomfortable. Oil-based lube could probably fix this situation though.
As for the actual product, it was delivered on time, and the packaging was nice. It fit on my husband nicely. But, the ribs and bumps seemed to rub me raw, and not in a good way. Not something I want to use frequently, but it's interesting.
