Having seen similar items locally (but at a much higher price), I couldn't resist the price Amazon offered, and sure enough a couple days later a rather large box was on my doorstep.  When I opened it up, I saw what appeared to be a bit smaller and lighter weight than I imagined (though consistent with the facts provided), but I quickly expanded the telescoping shaft and staked it into the ground.  Many other sprinklers fail to deliver the promised range, so I was surprised to find it exceed the stated coverage area (quickly fixed by dialing down the spigot).
