I bought one second-hand a couple months ago. It's neat and all, but between the poor software and the severe extent to which it darkens the rest of the world, it's a pretty resounding 'meh'. I still have hopes for using it for productivity, but it honestly doesn't hold a candle to the original Hololens. (Can't speak to the Hololens 2 yet; going to get one in a little while though, hopefully!)
