I'm giving this 4 stars because it looks like Vevor doesn't post any reviews less than 4 stars. The plastic electrical control box was cracked open in shipment.
Emails and messages left on Velor's contact us page about this problem have all gone unanswered. Phone calls have gone to a full mailbox. I have given up on any support from Vevor.
I guess I will someday fiberglass over the electrical box and see if there are any more problems.
I won't be buying any more products from Vevor.
