I bought the clarity aloft headset through them. They took the money and didn't deliver. After I contacted them they said they had a lot of fraud to deal with. It was time sensitive so I cancelled the order and got refunded. I later ordered it again having had to borrow a headset for a few flights and paid through PayPal. I had no problems at all. My only complaint is that they didn't know I'd been charged the first time and didn't contact me to say they thought there was a problem. I had to chase them instead.
I would order through them again but not for anything urgent and not with a credit card.
