Works great with Arduino projects and is strong enough to pinch fingers, so be careful. The mounting holes make it easy to attach multiple motors together or mount to a larger project. Currently using a few of these motors to create a robotic arm.

Product looks solid but have not been able to test it yet since the servo did not come with the screws to mount the u brackets to the servo.

Seems very high quality made doesn't seem cheap or delicate. One major flaw I added photos to try and demonstrate, is that the wire comes out of the servo on the side that has the moving bracket. So the mounting bracket is on the opposite side of the wire. The moving bracket side, has the wire, which gets in the way of the moving bracket. However as I tried to show in the photo this is easily solved by pulling the wire down, however, I can see that causing stress on the wire possibly you could damage the wire this way. Also if your motor was to swing to far, as shown, it could pinch the wire between the box of the servo and the moving bracket. Ideally, they could have ran the wire out the mounting side as this is more logical for having the wire out of the way of a moving part, no tension would of been placed on the wire, and depending on what you mount to, you could of drilled a whole into your project and ran the wire down through it avoiding any pinching. Other than that one huge design flaw, it seems very sturdy and good quality material. I'll be returning mine only because of the wire, if your able to over come and over look this, it's a great motor.
