This is the first "square" handheld I've seen, and the price is fantastic. Lots of creative uses for a handheld of this size. I will say, the lipo batteries are bit of a hassle, with special chargers ($100+ for a good one) and whatnot, but they are lightweight, do charge fast, and do last a long time once you get them in place. Just be prepared for a bit more out-of-pocket cost before it's fully up and running.
