I just got this meter and it looks like I have a used one. The battery was already in and the wires were twisted and just stuffed into the box. When I tried to use it the meter gave me inaccurate readings and it looked like they were cable glands. I wanted to return the item through Revain and they said the item was non-refundable! I called support and spoke to Chris, told him what was going on and confirmed it was non-refundable BUT he refused to refund the purchase price to my account. I'm glad I called her otherwise I would be stuck. Be careful when purchasing this item, I didn't find anything on the listing that said it was non-refundable.
