Yep, I'm just a sucker for a big difference in a claimed sale price from a regular price.
I just fired this up and so far it seems pretty cool. Took a measurement of my hallway and it was plenty accurate with my tape (within 1/16" or better), but the hallway is less than 4' wide.
You can hold the ON button and it switches to continuous measurement, vs taking "snapshots" each time you press the measure button. I stumbled upon this by accident as the instructions of course are annoying at best, but it's probably mentioned in there.
You can also reference off the front or rear of the unit, but I assume this is standard for all laser measurement tools - - this is the first one I've ever touched.
My biggest concern is support for this platform in a few years. I suspect Ryobi will just stop making the batteries sooner rather than later. But it's conceivable the batteries could easily last a great many years even with minimal use. At least it's easy to get them as one comes in every clearance tool along with a charger.
edit: oh and I'm not readily finding a way to have the unit just give me inches, which I'd prefer in many cases, eg 39" vs 3' 3". But I can live with that.
