Definitely does not run at the same speed with reversed polarity, but not a huge deal ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars great little motor *by D***S on Reviewed in the United States on June 1, 2023* Like others, I needed a motor with more torque than a standard 6v motor. I ended up getting three at different speeds. Not as quite as I would like it to be, but it is also not too loud. ### ⭐⭐⭐ 3.0 out of 5 stars Did not work as expected but great customer service *by R***J on Reviewed in the United States on August 28, 2023* I ordered this to replace a motor in an rc winch. It was the right size and the installation was easy. When I tested it, the winch had zero keep/brake. It would free spool. Update, the seller contacted me to troubleshoot and ultimately will replace. 2nd update, unable to send replacement. Refund provided.
