It comes with a lifetime motor warranty, a 5-year parts warranty and a 1-year battery and accessories warranty. Motor warranty is for lifetime for both the motor devices 8500 and 8500w.

My take is 8500 is the go to product when it comes to the pricing aspect. 8500 provides a security code feature where only users who have authorization to operate the device are allowed.
