i have been using my lulzbot mini, since Christmas 2015, so its been 2 years & a litte more than 6 additional months,& to be honest i could have asked for better,i can safely bet on going over 4-6 months or even more without any maintenance or problems,that you can rely on & can trust on its a high quality workhorse it can print finer resolution than most as small as 5% of a milimeter , this printer easy to use reguardless of what level of 3dprinting you are at
the lulzbots are built to last & be very durable when used properly
& their customer service is beyond phenomenal & they helped me with any problems i had even when my warranty expired, plus they offer 3D-Printable blueprints if any of the over a hundred 3dprinter parts i ever break so i can then print as many as i want.
they include all the tools needed, its packaged amazingly, it comes with a check list to ensure you got quality
they even shipped free resources for me to do a presentation so i had been able to educate a small group about 3dprinting it included things like sample prints, guides, fact sheets,reference materials , etc, & they do it because they care & love to educate people about 3d printing, so everyone can have a equal opportunity at 3d printing
i would not be surprised for this printer to last over a whole childhood, if you want a printer with minimal compromises i would recommend this printer
& lulzbot also has lots of tutorials,& i could not have been in a better situation when it comes to lulzbot
i would however recommend a retainer for the front plug but that's my only complaint , there is little to nothing to complain about.
