I got a free Zippo Blu through Marlboro last week and took it with me on a business trip to try it out.
1. There is no flame adjustment on it. One size fits all and that size is large. It worked well for my cigars, but a buddy grabbed it to light his cigarette and we think he lost an eyelash or two
2. Flint system is ok. It definitely take some getting used to. The whole flint and wheel sit on a platform, which would be the butane release. The first time everyone grabbed the lighter and used it, thier finger slipped off of the platform, and they lost the lighter. Of course some guys just fumbled a little bit, but one guy took out 3 cocktails and a lamp trying to protect my free lighter.
3. Feels much heavier than my Zippo with Z-insert (which I have owner for over a year without a problem). The entire lighter is larger. (both taller and thicker)
4. Small window on the side was great. Easy to see how much fuel was left. After three days of heavy use, it still looks like its going strong without a refill.
Overall, it was a nice lighter. If you like traditional Zippo lighters, this aint it. I still love my Zippo with Z-insert. I'll be looking for these lighters around my smoking haunts to see if anyone else picked one up. I have yet to see them in retail stores in my area
