I bought these and was one of many that had the issue of it shocking you. I mailed them back September 14 and USPS lost them. I submitted a missing mail trouble ticket a few weeks ago and they said I didn't provide them enough information?? Really?!? I gave them from/to address, tracking number, last scan location, Jamaica New York International Distribution center and described what it looked like and the contents. I assume someone at USPS stole it and it will never be found. So I am out $150 with nothing to show for it. I wonder if I make the case to Linsoul, if they will send me a new one? I already gave them the tracking number back in September, any thoughts on what I should do?
