## Product's reviews:
- President - Excellent to deal with,best price and received product promptly
- Review your thomson linear dm12-20a5-18ce purchase - Great pricing. Thanks.
- 12 volt motor - Bought this motor to replace failed unit on linear actuator on Grasshopper powerfold. Worked excellent, simple bolt on procedure. Saved $600.00 over replacing entire linear actuator!!!
- 5.8 inch actuator - It was exactly what i needed for the center window on 370 Sea Ray. will buy from again if needed
