That's not a brand I came across in my searches. I'll have to look into it.
CoreXY has advantages over the typical RepRap-style 3-axis movement or bed-slingers. The frame is more rigid, so the print head can move faster while maintaining accuracy. The enclosure also lets you print higher temp materials with less warping.
IMO the big advantage of core xy is acceleration. My old i3 clone could print fairly fast, but my accelerations are way higher now, which lets me hit my (also higher) max speed faster and more frequently.
Not to mention the footprint. Bed slingers need a much larger workspace area in order for the extruder to reach the entire bed area. I'm a bot skeptical of the printer listed above though. It has a really tiny bed and not that great of print speed. Plus looking at the page they list things like "5:1 gear reduction" three separate times (who cares what the drive ratio is?) which leads me to believe it's built with cheap parts and lacks a lot of features standard on even cheap Ender machines.
This is true. My 350mm^3 corexy is basically the same depth as my old 200mm^2 bedslinger.
