Have bought this charger blind and am actually quite pleased with the functions, the operation is similar to other standard charger, such as the Yuki Karate. It has just about everything you need, but an EH Balancer Board would have been very useful, which is namely not supplied. Even if you can EH directly insert into the front slot, it's pleasant, if one uses a Balancerboard, quite apart from the fact that the plug at some point ausnudelt it. The biggest point of criticism is the volume for me. At first I just 6S LiPo loaded, that was outrageously loud, but that is still outbid when loading 12s packs. When I put the charger into an adjoining room, close the door and 6s battery charging, I do not even too loud. Incidentally, the fan and the bearings of the fan to hear not very good, probably to be expected with an early exchange.
