MY flashforge creator has been in operation for 3 years. Apart from tiny amount of routine maintenance (bolt tighten, rod clean and lube) not had an issue with it that I couldn't trace directly back to something I did wrong.

About 1200 printing hours on it. So yeah seriousuly reliable. Moved on/off switcn to front, added print area cooling ducts. Apart from that all parts are still factory original.
It's an old model these days - so not huge build volume: 220x150x145 mm basically 9x6x6 inches. I have yet to need anything bigger.
Flashforge only do the creator pro these days and I'd probably take it over any of their newer models.

What's your budget ?
