Purchased a hero 10 black and all the mods, i paid for express shipping. Camera arrived in 2 days, defective and would not power on. Contacted support and RMA issued took 7 days for them to get it, 7 days to process. According to agent they shipped a refurbished unit. Worst purchase i have ever made. I paid for a new camera & fast shipping. It has been over a month and i am still waiting... they cannot refund me because they already sent out a refurbished unit that i have not received. Customer service says they will get with their team manager and contact me when they can find out anything.
