Absolutely useless, bordering on fraudulent. Made a dermatology appointment, received a message back saying they couldn't diagnose a skin issue online, so I should go to a real dermatologist. Okay... But then they billed my insurance anyway despite rendering no service. Don't make my mistake - avoid this scam and just go to a real doctor! Update: tried contacting them per their advice below, and all they did was send me a message with their terms and conditions. Avoid them.
