LED Light Show Gyroscopes (2-Pack)

Pros: none really

Cons: Not much fun at all. Other gyros available offer more enjoyment.

Other: Give it a miss. Of the two I received one was damaged, the other worked but wasn't much fun at all for my child.

Pros: Very attractive appearance, easy to use, did i mention fun?

Cons: Build quality could be better (little bit bent axe on one) vibration shows on higher RPM (because of unbalance inside gyro on PCB board)...

Other: It is great stuff for the money, fun, my kid enjoy it very much, me too...

Pros: Very cool light show and no annoying music. No launcher required...just skim it accross a table in one swipe and it will spin for about 30 to 60 seconds. Simple design uses centrifical force to push some contacts outward which then touch watch batteries. Batteries should last for a very long time, and if not, you can pop it open and replace them (if you do so with care)

Cons: The build quality is a bit poor. After alot of use, the plastic notch that holds the spindle at the top broke on one of them. However, in fairness, my kids and I play smash-up-derby with them to see whose will hold up and spin the longest.
Also the outside plastic edging can chip (with rough use) and unfortunately tend to be sharp.

Other: Very cool and very inexpensive top (remember, you get two per order).
Extremely simple to use and is all around fun to play with. Not as exciting as the dance-show type tops that have lasers and music, but since the launchers on those break very easily, I think these have much more longevity and are a better bargain.
I just bought six more!!
