Some of you mentioned wanting some real world feedback.
I've had this since fall of last year and have been putting it to the test. So far it hasn't so much as hiccuped on me. It is both a plotter and a CNC cutter. You can cut intricate parts from a drawing as seen in the photo or you can transfer a template to a drawing with the plotter function.
It is equipped with torch height control (For warped metal or surfaces that are not flat)....but to be honest I haven't started to use that feature yet and it hasn't affected me that much. To be clear, the torch does have height control, pierce height, cut height and transit height are all tume-able.
Quite honestly it does exactly what it's made for extremely well. One area it really excels is the plotting function. If you like to fabricate by making templates then this machine would be an absolute must. It works equally well cutting from CAD drawings. It's light weight and size make it quite portable. For example. I will be cutting some rectangles out of the surface of my welding table for electro-magnets. The arc droid will do that job perfectly for me.
Customer service is excellent. There is a forum on the ArcDroid website of users like us sharing information and techniques. The designer/owner is very involved and has responded to my emails almost immediately.
One more note: They now make a sliding table the ArcDroid mounts to that increases the cut area to 4'. For me a 4' x 20" cut area is plenty large enough for most things I do.
Pros: Light, portable, compact (good for tight shops), Simple to use, fairly trouble free. Excellent, Excellent customer service.
Cons: Small cut area, cost (I felt like it was reasonable),
Quite honestly this is my favorite tool in my shop by a looooooong shot. It has improved the quality of my builds and saved me a LOT of time.
Now that I have had it long enough that it has proved itself I will be buying the slide table and mounting it on a dedicated table. It will be compact though and that is one of the best things about this tool.
-If someone can kindly direct me how to upload videos I can post a number to time-lapse videos of it working.
