I've been using the standard (roughly) $25 KAW for years and love them. This newer unit is in the form of a "powerstrip" which.. includes a plug in cord, so makes it much easier to place the meter in an easy-to-read location. It also is lit, AND... unlike the original, stores the readings so you can unplug and move it around. (The traditional model, still available, resets to "zero" when unplugged.)
My only hesitation is that the one I purchased was intermittently dead on usage and I had to, at my expense, ship it back to the distributor for replacement. Aside from that big annoyance and concern, I love both versions and use them frequently.
(because of that hiccup I'd suggest checking the "return" policies of the store).
