I love these things. Fun and a great workout.
Thought mine was broken until I read the frutzing manual(!) and got it working. Very effective on my wrists after I’ve been typing all day. Works in both hands. Safety strap is included and very necessary as this thing goes fast. I got the LED colored lights version, useful to know how fast I’m rotating.
The item arrived in two weeks, in excellent condition. It conforms to the description. For use to see in the next few days, see weeks. I was very happy with the first one I bought.
I really liked the product I recommend
