Wordtracker predicts 263/day. Probably not worth much over reg fee at this point. Any bids yet?
Did you have to pay for this to be a featured listing? I wouldn't have recommended doing that for this name. If you had "laser" it would be a totally different story.
No real rule, but that's a pretty low number if you want a sale now. I try to go for over 1K/day, depends on the term. Just my opinion, maybe the name is better than I think because of it's brandability/shortness, that could be the case. Good luck.
