Several of my Ryobi tools sat unused for most of last year. None of them broke. They quit early, bogged down under load, or felt weak enough that I reached past them for something corded. I chalked that up to the sticker on the box, since I buy the packs and let the tools ride along and never expected much from a $60 tool. Then I started clipping High Performance batteries onto them instead of the compacts that came in the kits. Same tools, same jobs, different outcome. Three of them now live on the bench instead of in a drawer, and the upgrade cost less than replacing any single one of them would have.
