I've had a couple of these in the past. There are a few cons-the plastic tab under the cap retainer will wear out (a lil grease helps prolong) and if you catch the ignitor button from underneath it can pop off. Pros-comparing to the "official" Zippo version these have a larger capacity battery (& do last longer between charges), the electrodes are longer which gives longer life and stronger spark, and the best pro is the slanted spark area (may be a negative for lefties) makes lighting easier.
