This is the ABSOLUTE worst company There were several issues from the moment I ordered this servo. 1. I plugged it into my arduino and there was no turning of the servo or it just doesnt want to move. Upon further testing of upping the voltage to around 7.4, it started spinning continuously when it should have been stopped.2. I needed to solder extra wires on the servo and they said they couldn't with my price point, so they gave me extra wires and told me I could DIY it. They forgot the part where every single electronic is coated so I cannot even solder, and everything is welded together. To access a part I need to, you have to break off the motor which is not replacable. They also tried to put the blame on me that I am the reason why it did not work because I wanted specific requirements and that they couldn't do anything about it. Thankfully, I was able to get a refund and my money back. Beware of this supplier.
