What reviewers say

All three reviews are five-star ratings from verified owners of the Shaft A variant. Reviewers report that the motor fits and performs well in a Goosky RS5, with one describing plenty of power and smooth operation, and another calling it efficient and cool-running. One reviewer praised the seller's service and noted that connectors were included but screws were not. One review was written before the motor had been used, so it offers no performance evidence. Overall feedback is positive but limited in number.

  • + Fits and works in Goosky RS5
  • + Plenty of power and smooth operation
  • + Efficient and runs cool
  • + Good seller service
  • − Screws not included
  • − Limited feedback from a small sample
