SlipX Solutions Adjustable Better Soak Overflow Drain Cover Fits All Drain Types for The Deepest Baths (Silicone, White)

Works as described. Doesn't seem to leak and easy to apply. Gives me 2-3 more inches of water.

So glad I bought this! It does the job and looks good in my tub. No problem at all with the suction cups

Having read the reviews critical of the cover's sticking power, I carefully cleaned the surface and pressed it in place very meticulously. Took a bath and it worked great. Went to take a bath a couple days later, worked just fine again. Couple days later it had popped off and was sitting on the bottom of the tub. I pushed it back in place and took my bath and it worked fine. Couple days later, same thing: it had popped off, I put it back on and took my bath just fine. If I have to push it in place every time I take a bath, I don't think that's a big deal -- it cost less than 10 bucks, it works great at raising the water level, and its slim shape is perfect because it fits between two ridges on the tub that interfered with a larger, round cover. I gave it four stars because of the need to reattach it every few days, but it works great otherwise.

It works great! My overflow valve prevents me from taking baths where I’m fully submerged until now. Totally recommend.

It keeps the water from flowing into the overflow drain, so that's a plus. But it won't stay in place for longer than a few hours, so you'll have to place it again every time you take a bath. So I guess it works. I'm concerned that if it works this way brand new, it'll fail to work at all at some point. But I guess for ten bucks what can you expect?

Sticks and allows me to fill the tub to the top, not asking for much. I've had this for a while now, so it's durable.

The suction cups do not stay attached to tub surface. Very bad design

OMG! This is the best thing for bathtubs! I complained about the water level in my tub forever then saw this and bought it. I have NO problem with it sticking to the inside of the tub, just make sure you push on the little bubbles to stick and wellla! This is a must for making the water level higher in your tub do not hesitate to get it now!
