It's okay I suppose, received it on the 14 and tried it out as soon as it got here, I can feel it in my legs so I guess it's doing something, also it came with a scratch and looked like it a was fairly used but nothing like using little bit of disinfectant to clean it! I just don't like how it says new then when you receive and item and then you get something used when it stays that it's new but besides that it's not to shabby I will update if I have any issues with it or anything else!

Broke after used a couple of times. Can’t return the product. Cheaply made. Waste of my money! Do not buy. Save your money!

I love this disk and it is fun to use. I hold on to the couch and twist.

I bought this after many years of searching. (My grandmother had one decades ago)This one is rated for 400lbs. I weigh 250 and I hear it breaking beneath me. Very disappointed.

I find ab workouts to be a little boring, and I am always looking for something new and fun. I looked forward to trying this. I use it after my treadmill workout. On carpet, with headphones. So how quiet it is or not doesn't really matter to me. But mine, at least, is quiet. It has a soft woosh sound. It is not silent, but it is also not noisy. I use it with shoes on, but for the sake of this review I also tried it barefoot. With my shoes on it feels quite smooth. Without my shoes, in bare feet, it isn't completely smooth. It's hard to describe but it almost feels like you are going up and down a hill a bit as you twist. But with shoes on you I didn't notice this at all.I find it interesting that I definitely have a stronger side. It is challenging for me to twist continuously and vigorously without spinning around. Which makes me laugh as I struggle to straighten out. But, as a slightly fitter than average person I was disappointed that I just haven't been sore after use at all. Usually, any sort of a new exercise will find some muscle I don't regularly use, and that to me is one of the main benefits of doing something different. With this, nothing.After a few uses, I can say it is definitely a little gimmicky. I think it is meant for someone who is at the beginning of their fitness journey. Not sure it is for me. It isn't vigorous enough for a real workout, but it is hard to imagine doing what the people in the listing are doing, ie working, cooking, etc while on the board. Watching TV though is doable. I think the right person though could enjoy this.

The media could not be loaded.  This is the standard twist board version. Perhaps the upgraded version has readouts on the circular display? No matter, my wife and I eagerly hopped on for a spin.The board is stable and easily twists from side to side with little noise. The bearings are doing a great job of stabilizing your movements. As long as you have a flat surface, the board stays in place with the 3 rubber pads.What I like is that you control how much to twist based on your ability. The board does not fight you to return but instead you utilize your core to navigate the twist range. You can choose a small twist or even go in a complete circle like I did on the attached video. You have full control.We both like this twist board. Simple to use and easy to store. You can twist while watching TV with no issues. You will also be hard pressed to fall off as the board is low to the ground and your weight properly centered on the feet diagrams is very stable.Great addition to our exercise regimen especially as colder temperatures are coming.5 stars!
