Input: The product worked fine on the first day and now it doesn't work as described on the advert. I've never been so sore (both side) in my entire life. I cannot wear it for more than 2h. Other then the product itself, the delivery system was also misleading I choose a 5-8 days delivery when i placed the order but the product was delivered a month later. What made me even more annoyed was the fact that I had to pay for the post charges because apparently the sender didn't use correct stamp or pay the full charge. :@
Output:
Negative
