Item was received in a timely manner in excellent condition. it is a unique piece of equipment not found on other stores or sites. i love it! i am ordering another one! it is fun & provides enough springs for all athlete levels. i have strong fingers & it the medium & hard springs are still a great workout. i highly recommend this item!
Works really well, the instructions are not super clear. But you'll figure out the "charging" pretty quickly. Basically walk the inner wheel in the directions of the wheel with your thumbs, hold it there and release when ready.
I bought this after reading an article about how it helped another person's father. I suffer with familial/essential tremors and have taken the strongest anti- seizure medication that could be prescribed for 7 years. The meds worked for the first 5 years then the tremors started getting worse and my neurologist started talking about brain surgery...ain't happening. Tried thc but would have to be stoned like crazy for me to not tremor. Now when i start to tremor i use this for 5 minutes and no more tremors so that i can eat or drink without spilling. I have left this one at work so that i always have it where i need it the most (right now it's been 3 hrs since i last used it and i am holding my phone and typing this with zero tremors) and am ordering a second one for home next payday. Bonus for me is that not only has it helped with the tremors but i also have sever arthritis in both hands and it is helping with my grip strength!! !
