Ask HN: Favorite purchases of last two years? 413 by wyldfire | 1131 comments on Hacker News. I've abandoned all faith in reviews online. But the HN crew can give good advice and are extremely unlikely to shill garbage. Consumer Reports is great for finding which manufacturer/model to buy. But what product or service did you buy that you found really useful/entertaining? I'll start: I caved and bought a robovac. Wow, unlike many techno-gadgets, this one really delivers. Real utility, not just taking up space. Low maintenance, runs while I sleep, and the floor is just cleaner.
