The Keychron B1 Pro Ultra-Slim 75% Wireless Keyboard is a highly portable and lightweight keyboard designed for seamless multitasking across various devices. With support for 2.4GHz, Bluetooth, and wired modes, it offers incredible versatility for users who need to connect multiple devices simultaneously. Thanks to its ZMK customisation, you can connect up to four devices, including your phone, tablet, PC, and Mac, using three Bluetooth connections and a dedicated 2.4GHz dongle. This flexibility ensures you can switch between devices effortlessly, making it ideal for professionals who require reliable, multi-device support.

The B1 Pro also boasts a remarkable battery life, providing up to 1200 hours of continuous use, or around 8 months with 5 hours of daily usage. This extended battery performance allows you to use the keyboard for months without frequent charging, ensuring it remains a dependable tool for long-term use. Additionally, it supports uninterrupted operation while charging, so you never have to pause your work. For gamers and fast typists, the 1000 Hz polling rate on the 2.4 GHz connection delivers a responsive, cable-free experience, while Bluetooth 5.2 offers smooth connectivity for multitasking across devices.

Designed for both Mac and Windows users, the B1 Pro features a Mac layout but remains fully compatible with Windows, offering the same multimedia and function key capabilities that Apple users expect. The concave keycaps, optimized for ergonomic typing, reduce input errors and ensure comfort, while the ultra-thin 5.2mm frame and 3.2-degree typing angle provide stability during extended typing sessions. Additional features, such as a silicone key skin for protection, emoji shortcuts, and the Keychron Launcher for keymap customization, make this keyboard a versatile and user-friendly option for everyday use.

Good plates but someone can't count
Style: 600 Count (2 Pack of 300), Size: 300 Count (Pack of 2)
Good plates, exactly what I needed. Sold as 2 packs of 300 but only 1 pack of 300 arrived. Since this is an Amazon deal, they don't give you a way to talk to a seller, only let you make "suggestions" for the future. Only recourse given at that point to to return for a refund. It would appear sending half the order is a common issue with this particular offer.

Great value!
Size: 10 Inch, Unit Count: 372.0, Size: 10 Inch, Unit Count: 372.0
Nice paper plates! They’re sturdy enough to hold two fairly heavy sweet potatoes safely in one hand, they have a waxy layer so liquid and gravy don’t soak into the plate. The design is nice. For the price and the quantity alone, I’ll keep ordering these!
