After I got my uncle for Christmas a Gyrotwister, I wanted to set myself one too. The GyroTwister my uncle is even after multiple use (about 2-4x a week about 15min) in a very good condition. Of course I expected my Gyrotwister the same. Unfortunately I was very disappointed with the quality. After a short time the Gyrotwister was unnaturally loud and no longer ran around. Meanwhile, the GyroTwister can also start with difficulty only. I do not know whether my Gyrotwister there is a manufacturing defect or has not yet abated if the quality of the product. From my side is unfortunately sent back.
3 stars there it anyway for the 1st and 2nd good idea to functioning Gyrotwister my uncle ;-)
