"Hard to get contacts to match up"2.5 starson by dargreg
Pros: The batteries last a pretty long time. It will save you money over the long run.
Cons: Getting a full charge is difficult.
Summary: I would never go back to standard batteries, but I find this unit to be very frustrating. It takes a while to match up the connectors so it will charge. And even once I do, the blue charging light typically turns green within a minute, long before it has reached full charge.
