I agree. Last time I used it in mid 2014, it was unusable. I spent more time trying to fix and work around its bugs than I would have building a VM from scratch, so eventually I gave up and went back to my plain VM. It's great for trying stuff out, but anything that needs to work for more than one session was extremely problematic with a lot of networking problems that required destroying the VM and rebuilding it constantly.
