I think the magic of this thing is for folks who are really limited on space, and want to do both B&W and RA4 printing. I mount my 4x5 to a copy stand and use this thing pretty often. It took some getting used to, but I have made some prints im proud of with it. The most fiddly part is focusing on the intrepid 4x5 because it's on the back of the camera, but if you aren't printing big it's not a huge deal. Id love to set it up as a projection style enlarger instead of on a copy stand at some point, but that requires more space than i've got! It's a pretty nice piece of kit, especially if you have a copy stand already. Trying to set it up with a tripod to print is annoying!
