It’s half a year old, and is operational. I’ve only used about 2-3kg of filament (ABS and PLA) on it so far. The main reason I’m selling is just because now that I’ve gotten used to 3D printing a bit, I’m upgrading to a printer with a bigger bed, and one that’s a little more customizable. It’s really easy to get started from this printer, but that’s also what makes it not very customizable. This printer is great with ABS, less so with PLA. I recently (within the last month) got a new printer head for it since I was running into issues with my original one.
