Tinkering Supplies Continuous Rotation Servo

Sent promptly; item is as advertised.

You are buying a Parallax Continuous Rotation Servo.I bought it from The Scientific Tinkering Store because i needed it as soon as possible for a school project and since i have prime, then this worked well for me. However, if you need one and you aren't in a hurry, you can buy it cheaper from the Parallax's website.The other choice you have is to buy a really cheap servo and modify it, for which there are plenty of tutorial out there.Still, the servo is great and work amazingly.

Did not use it but seemed to work perfectly...

The price is high!!
