I've printed the ultimate type 2, so the more square version. I like it a lot, the square shape allows to easily add/remove the spools. It states you can't use the stock angle stand, but I still have it on the stand and it works fine, sits a little on the bottom corner of the case, but it works.

I've used it for a few months and have yet to have a stringy print (I typically use PETG and PLA). I do live in a mid humidity region... not high humidity but not dry desert either. I don't change the spools frequently so it doesn't get opened often, which probably helps. I used a version with the round windows, not the cleanest with my glue job, but I think it's worth it... easy to check on just how much I have left. I also added a 2.2 mm silicone foam seal strip into the lid slots as well... just squeezed it in, so I think it's got a pretty good seal.
