Review on Motor Controller Variable Adjust Control by Mario Schultz

September 2020. The other is not out. The second worked every 20 minutes and then died. The 3rd is working now and at it for about 45 minutes, I'm still skeptical but I couldn't find any other option. So if you have any ideas let me know. UPDATE October 2020: So the 3rd was used less than 3 hours total and it died, I came back to issue a refund and the refund window closed yesterday! We are trying to change the DC motor speed to grind grain with the Country Living Grain Mill, this item was terrible for that purpose!
