Review: Good quality.
Review: This is an awesome product! Makes for great party conversations and competitions! I was hesitant about not picking a model with the electronic counter, but thought that since the counter faces your palm anyway, that you would no see it. There are 3 colors to help you know how fast you're going. The red LED indicates that the spinner turns at 1000rpm. The "purple" LED" indicates that you're at 4000rpm. When the spinner changes to a solid blue light, it means that you're turning at 7000rpm, which is about half the maximum speed of this model. I try to keep a cruising speed while this spinner stays on the blue color for a good work out! Yes, your forearms will start to feel the burn! :) I wish there could be more LED in this model to indicate maybe 10 000rpm and then 13 000 rpm. Still great gadget to train your grip!I highly suggest the autostart function! You just crank the rotor with your thumbs instead of using the red pull-string that comes with the other models (nothing to lose).
