Good value, lightweight--you can pick it up with one hand easily. I like the shelf, though I didn't use it as often as I thought I would because my shower head has a hose on it (which you really need if you need one of these). The shelf came in handier during the period when I couldn't put any weight on my foot, when it was too hard to even turn around for fear of overworking the bad knee on my other foot. It's easy to adjust, and while I'd still like a stool that's just a few inches taller, this is probably the tallest one around. And the rotating seat was particularly great when I brought it into the kitchen, so I could sit down and do some food prep. At first, I was suspicious of the complaints I read from people who said this was so DANGEROUS. I had it in a flat, non-slippery shower stall in a cabin. It was fine. I couldn't figure out what the problem was. Then I took it home and put it into my tub/shower combo at home. The tub slopes toward the drain, of course, as all tubs do. What I learned--almost the hard way--was that the seat, which is pretty smooth, may be fine if it's completely flat. But in the tub, which doesn't SEEM very different than a shower stall, I sat on the stool and was fine for a while, when I wasn't really moving, but as soon as I moved I completely slipped off. l'm saying it was impossible to stay on the chair, and I wasn't doing anything unusual. I was just rinsing myself with the shower head or reaching for the shampoo. And I tried to sit back on it, but once you've got a certain level of water on the stool and on yur rear, it's IMPOSSIBLE to assure yourself that you aren't going to slide off at an inopportune time and land on your rear or, worse, your head. And if you're recovering from an injury or surgery and are supposed to keep your weight off your foot, forget it. You will end up in the hospital. I was thankful that I was now able to bear some weight on my injured foot, and that I had something to grab on to when I slipped. Then I realized the reviews were right, and the only way to salvage this accident waiting to happen would be to put a washcloth on top. This is an unacceptable level of hazard for a consumer product, and I would recommend that you NOT purchase this item, and that it be reported to the CPSC. THIS IS TRULY DANGEROUS. The thing is, it wouldn't be difficult for the manufacturer to fix it. Put a layer of silicone on top. Shape it slightly like a bowl. I can't imagine they don't know this thing is a problem, and once the first lawsuit is filed, it will be off the market. Why not just FIX it now? offer refunds or fixes to those who have already purchased it, and apologize? It will be a lot cheaper than dealing with the litigation waiting to happen. Some also complained that the thing got moldy. There's also an easy fix for that. Since this is what I have, I just try to remember to turn it sideways so it can drain completely. But this is also an argument for a better design: slight bowl shape to the top, and for pity's sake, SOME DAMN DRAIN HOLES!! So you can drain the water from the seat (safer, more comfortable, and LESS LIKELY TO MOLD. It also needs drain holds on the structure beneath the rotating seat cover (safer, less likely to mold). Come on guys, some product testing? Some corporate responsibility? Honestly, if they fixed these things--which they should have done before they manufactured, and might have done had they thought to test it out more thoroughly--I would give it five stars. It is otherwise well built, easy to use, easy to adjust, and the shelf is thoughtful. Better yet if it had a little caddy attached to the structure to hold your shampoo, soap, conditioner. It's otherwise a great product at a great price. But the slippery seat thing is a dealbreaker if you don't already have it in your home or don't happen to have a washcloth handy to slip under your butt before you sit. Bottom line: Either this manufacturer or a competitor should develop an improved design. And the manufacturer might want to consider their liability.
