Old news. The latest SMC packs are excellent. The puffing problem may have been packs bought from China/Hong Kong that were cheap copies using the SMC label.

On second thoughts, please go ahead and believe this wrong statement, go and buy someone else's pack, and then I will be able to beat you with my SMC pack!!

Seriously, SMC is a very good cell, good price, no puffing problems and excellent performance. HTH
