Maybe, but quality is hard to measure. I just bought a Creality Ender 3 Pro for $180 and the print quality looks as good as anything I've seen from a Prusa or even the Ultimaker at my university. It's got a larger build volume than this mini as well. It doesn't have some of the comfort features, such as auto bed leveling or wifi, but if you really want these you can add them in and still be under the price of this mini, not to mention that the cantilevered design of the mini is almost certainly less stiff than the i3 style on the Ender 3.
Its the parent who is clearly marketing different product in multiple comments around the thread. I was just annoyed that i had to read thrid comment about how great differend product is
