Powerbar 2 Review
Not strictly technology, actually not really technology at all. The Powerbar 2 is one of those products you want to tell people about. Essentially, this is a pull up bar that fits to your door frame and requires no screws and almost no assembly.
This updated version has introduced flat rubber pads to prevent marks on your door frame, and new plastic mouldings to prevent damage to walls. The website claims it fits on 99.5% of all single doors anywhere in the world. The powerbar takes 10 seconds to put up or take down once you have worked out how. Once it’s taken down and folded, it’s easily storable. This is a solid, well designed product that vastly exceeded my expectations.
