Query: Manufacturer will not get back to you...

Worked for about a three weeks. After third week it went of line twice third time I tried to reset it will not come on. Tried different outlets unit will not come on at all. Tried contacting manufacturer never got back to me. Luckily Amazon customer service was able to help me return the item before the thirty days so I could get my money back. Thank you Amazon, not happy with manufacturer. Amazon customer service also tried reaching them no answer. I will be purchasing a different unit from a different manufacturer.
