Sonic-Disk Hand and Arm LED Fun Exerciser

Pros: Great toy. Good built and very funny.
Good sound and led colors are very beautiful.

Cons: There is a little piece of plastic in the center of the toy. You should remove it to lights work. Its not easy to discover that because this plastic piece is very small.

Other: Buy 2 or 3. For the price, you cant go wrong. You may give them as a gift for kids. I can bet they will be the funniest toy in a party.
There are different colors: sku 4123 and sku 4137.

Pros: Fun toy/exerciser. Hold in in both hands, spin in in either direction, & then pull apart to make it rotate as fast as possible, & the LED lights in the wheel will glow a little. You have to get it rotating as fast as possible for the lights to glow longer.

Cons: I don't know what the 'Sonic' in the item name is intended to convey. In any case, there is no sound as another review seems to suggest; just the LED lights which light up when rotated fast enough.

Other: Fun to play with or for gifting.
