I have the Hitachi 14.4 volt 3/8 inch cordless and am satisfied. If the 1/2 inch is built the same ... Plenty of power and reasonable battery life, but then when I bought it they were offering a "rebate" of a third battery free, so unless I forget to charge them as they go down and cool off, I'm not likely to run out of battery. BTW, every cordless tool I've ever owned, regardless of brand, said to NOT charge the batteries if they were hot from just being used; let them cool first, so there must be something to that.
