Speaking of which, I have yet to see a consumer battery charger that isn't incredibly cheap feeling. Even ones for charging different chemistries or that let you set current rates are a mess of low-quality molding and cryptic button presses.
Build quality seems fine, and I've been using them for decades without a single failure, so I've never seen any reason to even investigate alternatives.
