I have used these same chargers before, and they honestly are decent. They do all of the functions you need for most lipos used in nerf and are decently good and fast at doing it. However, for $15 more if you have the money to spend I would recommend the Team Tenergy TB6B and can be found on Amazon etc... and I hope Luke will start carrying them. They do a whole assortment of lipos up to 6s and this means you have enough power to charge multiple 2s or 3s lipos in series all at once. It can do many functions like discharge, charge, and can do most chemistries like lead-acid, lipo, NIMH, and other nickel cadmium battery types. This charger is good, but if you have $15 more to spend definitely get the Team Tenergy TB6B.
