It arrived in perfect condition and well protected. It should be noted that 'Teeth' refers to the gear slots in case anyone is wondering. If you want to change the motor, first count how many slots or 'teeth' you have to know which one to order. In my case, mine had 12 teeth.The replacement is very good, I recommend buying it!

The motor is exactly as described. I’m using it to replace a failed motor in a small cordless mini chainsaw. The original motor overheated because the plastic cooling fan melted and detached from the shaft. With this replacement, the saw now works like new. However, this motor also uses a plastic cooling fan, so I know the saw should not be run under heavy load for long periods to avoid overheating.

It was cheap, arrived fast, very well protected. its in place and works ok for now. Good business. Be carefull because the 14 teeth gear has 2 different sizes. Don' t get the wrong size.
