Opinion on a BR Host

[Scribble]

Hey guys,
I'm looking for a blueray host that takes 2 AA batteries or 14500s. I like the longer style and was thinking that one of these might do well. I did a search but didn't find much info. Has anyone had any experience with these? (Sorry, I can't post links yet, skus are for dx.)
