They’re actually great machines. The CoHesion project and other open source and user-led efforts to make it better are great. It lets you start with an operating machine that you can than turn into a really good one without going the build from scratch route.
I’ve been surprised that the Muse & the Dremel haven’t taken off yet. It’s been 3 or 4 years - they should have been pretty popular by now with the Glowforge delivery delays and now their past few years of shipping at volume. Surprised the competition isn’t making waves.
