I'm the one who asked about it on jenius' youtube channel. Thank you, jenius, for asking on my behalf.
I'm wondering if it'd be alright to just try dunking the entire head in hot water and seeing if it loosens up the joint a little bit. I'll certainly be trying that once I get my hands on mine again since it's boxed up and on a plane to a new home right now.
I'd really like to be able to drill in a couple pins into the lasers' pegs to reinforce it because right now the softness of the lasers doesn't seem like it'd be able to handle being swiveled too many times without twisting right off. Why they didn't just include hard plastic lasers I don't know.
Otherwise it's a really great toy that I don't regret buying.
