Customer support is terrible
Customer support is terrible. My Delta 3 is defective, and after taking the time to do extensive tests, I realized that it was only able to hold 40% of its original capacity. When contacting the customer support (only by email), I was offered a partial refund (relative to device age) and asked to provide my credit card information (over email!!!). In the end, I now have a defective device and cannot do anything about it... Clearly, it's a scam.
