It seems to work for me with standard wood glue, but I tried some craft glues in there, and one (I don’t remember which one) definitely did not drain back. There seems to be a sweet spot where you need to have enough glue in the whole thing to get effective output, but not too much that it doesn’t “pull back” what’s in the tip. I have found that the tips definitely need to be covered when not in use, otherwise, I think the glue dries faster than it drains from the tip.
I haven’t had any problems with splitting, but I’ll definitely have to keep an eye out.
Regardless of the BabeBot, the GlueBot is great for larger woodworking projects.
