Great customer service
Ordered 2 replacement batteries for my Ruko drone. The batteries were bad. One would not charge, the other has a very short fly time. Contacted custome service. They sent new batteries. Shipping was a bit slow but the new batteries are good so far. A little disappointed that the Ah rating is a little lower than the original batteries, so a bit shorter fly time, but still adequate for most of my use. Overall I am happy with my drone and replacement batteries. Customer service was very good. Very pleasant to deal with, very friendly.
