I have owned this charger for a few months, but am amazed by what you get for the money. You can spend a lot of money on charger or a little, but nothing out there touches this one at the price. In fact, this charger is nearly identical to the Traxxas 5 amp digital charger (which costs $100 more) with the exception of the external power supply and USB port. It's so identical in fact, that I downloaded Traxxas' PDF manual for their 5 amp charger from their web site to learn how to use this one - the menus/features are exactly the same. Note for the power supply that I ordered the one they sell here only to find that a certain very large online retailer sells the exact same power supply (I already owned one for another application and have confirmed it works) for less than eight bucks. (search for the specs - 12 volt 5 amp) Not a lot cheaper, but worth mentioning.
I've only charged NiCads so far, but it has worked flawlessly, and I've just ordered a 2nd one so I can charge my 2 new Lipos that I also just ordered from Value Hobby. I'll probably get 2 more of these when my son gets his new Truck for Christmas! I love this charger and I love Value Hobby!
