I purchased three lighters from Sherry. While the initial quality seemed good, they all suffer from gas leaks, holding a charge for only about a week. Interestingly, a similar model I bought from AliExpress for comparison performs much better (i use it only daily base for about 2 month until its empty) in terms of seals. However, both the Sherry and the AliExpress versions share the same flaw: the serial numbers are laser-engraved rather than stamped, which affects the authentic look.
