This is the second 4 cup turner I have purchased. I use them both often and leave them running a minimum of 6 continuous hours at a time. No issues at all and assembly is fast and easy.
This product is great! Only thing I wish I could change is the ability to remove the arm to paint the cups otherwise it works well and was relatively easy to assemble.
If you are only gonna use this for small orders or home use. It’s perfect size, makes zero noise, pretty straight forward for using. If order it all over again.
