hhhhhhhhhhmmmmmmm.......BrandSniper is interesting but I think it transmits opposite messages..let me see if I can put it down into words..
A sniper is someone who is very skilled at hitting a target ( don't like the idea of killing someone... )
so it would say you/the website is really good at something related to brands/branding...but what is that " something " Did you think about it? I mean are you planning a BB-like website? Or would it be something different?
At the same time a sniper is a sniper...someone who kills people right? So that doesn't communicate a very positive message; at least for me but it could be different for the American culture which is used to guns & Co.
Did I make my point? So I like it but I don't at the same time. If it was mine I would probably try to develop it so that a potential buyer would get over the name itself paying more attention to the business/website/income.
Celluair is a strange one but I think i like it too. I don't know what you could use it for but if I were you I would pay a lot of attention to all the scientific/medical news and to everything related to mobile phones.
GOOD LUCK!
