Satechi has introduced the Slim EX1 and Slim EX3 wireless keyboards, both featuring a rechargeable battery that is easily replaceable, a rarity among ultrathin keyboards. The lithium battery can be accessed by removing a Phillips head screw on the back, allowing for simple swaps when the battery degrades. These keyboards offer additional features such as automatic key remapping for Mac or Windows, connectivity to up to four devices, and quiet scissor-switch keys. Available in black or silver, the Slim EX3 is priced at $69.99, while the Slim EX1 costs $49.99, and both are available for purchase on Satechi's website and Amazon. This matters because it addresses the common issue of battery degradation in wireless keyboards, offering a sustainable and user-friendly solution.
