I got my first order 3 days ago. And one of the items didn’t work. I sent an email to the customer service team and explained the situation. They answered without a delay and promised to send out a new piece till the end of the day. No other questions asked. They didn’t even ask me to send the broken piece back. So easy. I was a bit surprised. The second package arrived an hour ago. It works OK. I checked everything. So what can I say? Their service is the best I saw. No complaints. But still there were certain quality problems. So three stars.
