Summary: I have owned this for about a year now and while it hurt to purchase I am now buying another one for an electrician that works for me. It is that good! The batteries charge in about 10 minutes (or less). The clutch is accurate and it is strong enough to drive a 1 1/4 screw flush into a 2X4. My only complaint it that since the Lithium Ion battery is so light and the gear mechanism so heavy duty the balance is not great.
Summary: I debated getting this screwdriver for a very long time due to its cost after seeing its predecessor in a store and liking the feel of it as it is one of those tools that makes you say "Ooh, well made tool!" when first picked up. Now after having it for a couple years, I wouldn't be without it as I didn't realize how much time I was wasting with a manual screwdriver.
Summary: I bought the hitachi lithium screwdriver and it broke within the first week (I tend to work my tools hard). I later bought this one and it's been going strong for a few months now with no problems at all. I'm an electrician and I use this practically every day because it takes the work out of - this sort of work... ...recommended.
Summary: This Panasonic actually retails for over $300. If you are using a manual screwdriver on a regular basis and can afford to upgrade to this model, do it. Highly recommended. Everything about this is exceptional. Surely beats those Black&Decker $25 models in almost every aspect. Highly recommended. The only minor inconvenience is the fact that the case that is provided is molded, so you cannot use it to carry additional tools. Trust Panasonic, it is used #1 in Japan.
