'Buy cheap, buy twice' is a common maxim in the tech industry. The idea being that while the idea of saving a little money may be a short-term gain, you'll eventually become dissatisfied with the product, or it'll simply break, and you'll end up buying another one and spending more money than you would have if you'd just forked out for the better quality thing in the first place. There are, however, some products that manage to be both cheap and of good quality, though they can be few and far between and often include a little corner-cutting along the way.
Which brings us neatly to the Xiaomi G27i, an extremely cheap IPS monitor. It definitely lacks sex appeal in its specs—for a 27-inch monitor we'd usually be expecting a 1440p resolution, and the Xiaomi is defiantly stuck in 2015 at 1080p. But it does sport a 165Hz refresh rate and, at just $140, would make an excellent budget choice if you're into pushing lower resolutions at many frames per second. And chances are that if it's at this price already, future sales are going to drop down mighty close to that $100 point.
