I have several Hobbywing BL setups and really like them. The ESCs are simple to adjust with the program box (simple LED number display). The motors are decent 2-pole motors. There are much better motors out there, but for the price, they work great and run much cooler than Feigaos. So far, the failures of the HW ESCs have been attributed to a known cause that can be avoided as opposed to failures of other ESCs that just go up in magic smoke (aka unknown). Overall, no more issues than any other brand. For the money, they're great. But customer service is not local and you need to contact HW in China if you need anything.
