What we can't tell you from specs

Build quality, app reliability, customer support and how a battery holds up after years of use don't appear on a spec sheet, and we haven't tested these units. Read each maker's warranty terms and cycle-life spec, and check the listing for the exact model and capacity before you buy: brands sell several versions under similar names.
