Excellent customer service
From ordering to delivery, I was kept fully informed of the status of the shipping. When my endoscope camera arrived I was disappointed that it didn't work so I immediately shot off a complaint. I got an immediate reply and a replacement camera was sent the next day. A couple of days later I installed the software on another phone and found that it actually worked! I contacted the customer support to cancel the replacement camera but there was a communication error and they thought I was still unhappy and offered me a partial refund (on top of the two cameras I ended up with!). I couldn't be happier with the customer service. I should also say that the phone it didn't work on is an Oppo A38, so if that's what you've got, don't buy one of these endoscope cameras!
