First time using your company and I am incredibly impressed. You sent instructions that were easy to follow and emailed me a PDF copy of the instructions. The packaging was great and the product is definitely heavy duty. I've never actually had a company send such clear instructions and make sure that I had a PDF available via email as well. Thank you. You helped us in in a unique situation that we had not experienced before with improper voltage

Hi, the only thing I would prefer different, is if termination points were not mechanical lugs. My preference only. I'll be sure to order this next time, otherwise everything else was great, works great, shipping was on time!
Thank you!
