Question: Does it work
Document: It was kinda clumsy to put together. The tools that came with the pkg weren't very helpful, so I used my own. I do use almost daily for a gentle massage. I would recommend for anyone looking for a way to relax and wind down after a though day at work.
This product seems to work okay but the screws and holes on the product did not match accordingly, 2 screws would not properly fit into the hole for it. The speeds are okay but when trying to perform certain stances if you take you hands off of it, it will shake, and yes I have it leveled on the ground in case you were wondering, but overall I guess it works fine.
I love this machine!!! I work as a personal trainer so I am very active. I planned on purchasing this product as an compliment to my daily workouts and I am glad that I did. I naturally have very thick skin that makes it difficult to see my muscle tone without flexing however, the crazy fit has helped with this problem allowing my muscle tone to be more defined and tighter among many other things. The best $200 sum dollars I have every spent!
wonderful way to exercise....just stand there. great for older folks, people that can't get around well, or people that have no place to walk for exercise. i've found that i can use steps a lot easier than i used to, able to get around better. great product.
power switch failed in 3 weeks. slill good machine for the money.life is tough and then you die . have a good day
it has great, strong, handles that you can hold on to. I have enjoyed using it
easy to operate and fun to do!My 15 yr old grandson(he has mechanical abilities) put this together in 30 minutes although it would of took me(female-71)at least two hours.
easy and fun---relaxing vibes--I have not had it long enough to  tell if it is beneficial for my health. I bought it for my circulation problem. No maatter what it does , I like it. and the price is right ! I reviewed several other brand machines and this seemed the best value for the money. Why spend thousands of dollars when you can buy this from Amazon at such a fantastic price. my opinion is that this is a very well built and sturdy machine.
but it will get the job done.
and it rocks ,I use it a lot and its very good for therice you cant beat it it is nice looking too
