My first mod with a battery I had Samsung 25r's, I'm lucky that the B&M I go to refuses to carry Pipe Bombs like eFest.I can relate to that, I know LUC is a good charger but won't buy it on principle, just because it's Efest.
Got to admit that when I first started I had 10A Efest reds, but didn't know any better back then.
As for chargers I have a couple of Nitecore's but my workhorses are Opus BT-C3100's, they'e excellent. Big selling point for them is that they have a built in fan to keep things cool while charging.
