Summary: I have owned the driver for 21 years. On my 3rd round of batteries. The adjustable torque settings are great, I can use it in building my own computers and avoid stripping screws yet drive screws and lag bolts through 1/2" drywall without problems.
Summary: Awesome. Long battery life and powerful. Been using this product for years and I'm completely satisfied. "It's not 18 volts... it's only 2.4 volts, sounds too wimpy and too expensive". Wrong. Try it, You'll like it!
Summary: I paid 79.99 for a Panasonic EY503B 2.4-Volt Cordless Drill & Driver. This is a lot of money for a screw driver and I would have expected a professional quality tool for the money. What I got was a hand held tool that has a poorly designed forward-reverse button.
Get the Milwaukee. Same screwdriver. Better warranty!

Summary: I compared this Panasonic screwdriver with the Milwaukee 2.4 volt 6547-22. It's basically the same screwdriver. The Milwaukee is also made in Japan. With the Milwaukee, you get two batteries, a fitted case, and three bits, including a 1/4" socket adapter and drill bits.
The best; makes the guys at Sears and Home Depot envious...

Summary: I've used the EY-503 for a couple of years while doing repairs on hardware for a major computer company. It's an impressive tool with great torque settings, two speed selections, and a really comfortable pistol grip.
Summary: The 2.4V wireless panasonic driver made my job easy and don't worry about the 2.4V, which must be proven to be more powerful than you expect. It was perfectly working for my tedious boring job at home. If anyone who interested in electric tool for hobby or whatever, try to own it.
Summary: I have used this driver for the last eight years as well as some others on the market, nothing will beat this unit. I am on my third driver now, not bad considering that I use this driver literally at least a dozen times a day. I use it in my work as a major appliance tech.
Summary: I've owned my Panasonic 2.4v screwdriver for about ten years, albeit unused for the past 5 or so due to lack of fresh NiCd batteries. Anyway, the EY503B was the best lightweight cordless screwdriver you could buy back around 1991, two speed with torque clutch.
