Review on Battery Universal Recharging Rechargeable Batteries by Bhushan Barkley

I've been using this charger for a month now and I'm impressed. I've had 6 different chargers over the last few years (some cost twice as much) and this is the best by a mile. Trying to charge 4 18650 batteries at the same time would take 10 times longer than with this one. Only time will tell how long this charger lasts, but if it lasts a year I think it's excellent.
