I’ve had my printer InquisitivePup for just over 2 months now. The three weeks or so were great, printed all sorts of parts in all resolutions, white and black, then had problems with dust on the mirrors; customer support has been great, however, as has the forum with its many active and helpful users, and the printer is up and running again since a couple of weeks.
I can echo @Francesco_Pessolano 's comment about nerves when dismounting the tiny, delicate internal mirrors; equally @JasonSpiller 's comment about it not being the easiest machine is right on the money… but so long as you don’t expect a printer that is as plug ‘n’ play as a laser printer (don’t forget they’ve been around for way over 30 years… just a liiitle bit longer than Formlabs!), AND you are prepared to put in some time to climb the learning curve, I believe you will be very satisfied.
