OXO Good Grips Bathtub Drain Protector

UPDATE Oct, 2016:We now have three of these, two for tubs and one in the wash basin my wife often uses to wash her hair. It fits perfectly over the top of the pop-up drain plug, allowing it to lift just a little if you push the plug all the way up, but still ride low enough at midway to let water drain and make a good seal with the silicone ring. There’s no problem with it sliding around, because it’s held in place by the pop-up. Those drains are soooo hard to clean if hair gets down there. You can still close the drain when you want without removing the unit, but if you’re washing your hair in the sink, make sure the stopper is not up too high.Original Review:I have old fashioned porcelain tubs in my “vintage farm house”, and the drain is rusted and jagged, so it grabs hair and makes it stick, causing a clog very fast. My wife has hair to her butt, so this is a constant problem. I certainly don’t want the wife to get rid of her beautiful hair, so something had to be done!I first mistakenly ordered the Oxo shower drain protector, which was too big and hard to keep in place. It caught a lot of hair, but still allowed it to go under sometimes… longer between required cleanings (a nasty nasty job) but it still happened.When I saw this one, specially made for bathtubs, I read all of the many reviews and was prepared for problems that others had seen. I carefully measured my drain, which was exactly the right size, and I saw that the tub had an indentation around the drain which should hold the protector in place. I ordered the product (this one) and it fit perfectly. It stays in place, not because of the silicone ring, but because the tub has the mentioned indentation. It is easy to clean just by either sweeping your fingers across the top to pick up the hair or by lifting it out and wiping it into the trash bag.After 3 weeks of use, I took it out yesterday to see how much hair was sticking to the rusted jagged cross-bars in the drain and it was still completely clean! Can’t ask for more than that! I’m a very happy Oxo customer!
