Last year I purchased for a ski trip a box of 20 sets of disposable hand-warmers from this company.The label says N-Rit and they are manufactured in Korea.
They never got warm. When I came home I called the company and spoke to Jerry who is probably the owner. He sent me another box which I took on this year's ski trip. They didn't get warm either, although they were well within the expiration date.
I called Jerry again and he readily admitted that they were defective and he wasn't going to reorder them but would allow the stock to dwindle. Does that mean he is still selling them to unsuspecting customers? I hope not! I politely requested a refund and he refused.
This is not a company that cares about its customers.
They are suppliers of so-called ecological outdoor equipment.I would never buy anything from them ever again and neither should YOU.
