I bought this printer after sending back a Printrbot model I was never able to get to work properly. Maybe I had a lemon. I also found it too much of a science experiment, with the need to enter code to make some of the configuration changes and the like. In contrast, many of the most annoying requirements of 3D printing - such as leveling the bed - are automated on the Finder and also accessed via an LCD screen rather than mysterious code. The only issue I would mention is that I have had some nagging technical issues that required me to get some replacement parts - but the customer service is prompt and very responsive. They have replaced the parts that I was having trouble with at no cost. I also wish the print bed was a little bit larger, but that's hard to know until you find the design that's too big. Also, the built in filament holder is kind of cool, but the filament costs more than standard. I just feed my own filament from a rack, instead. 3D printing is still a bit of a science experiment, but I've been able to do some really cool things so far. The next printer I buy will probably cost twice as much and have a dual extruder, but this lets me figure out what i like and what I want in the future while still letting me have lots of fun. I often have it running nearly around the clock when I'm home and it's been really fun for Christmas. My wife's bows on her packages will all be 3d printed.
