Appauling customer service. Attempted to buy two gear stages that they decided to discontinue, after 10+ emails and nearly a week they said they had it in stock and would add to the website. They never added it, I then spent 3 weeks emailing and calling with no response. Ive been forced to buy a complete gear sets, motors and shafts to fit my project and has cost me a fortune. Do not waste your time and money with these people who clearly dont want your custom.
