Review: Great keyboard for the price - This keyboard is honestly such a steal. If you’re a fan of that classic Apple Magic Keyboard vibe but can’t justify the "Apple Tax," this is definitely the move. It has a really high-quality look and feel right out of the box. The spacing between the keys is perfect—not too cramped, so it’s actually comfortable to type on for a while. One of the best parts is the sound; it’s nice, quiet, and super satisfying, so you won't be annoying everyone around you. Plus, it’s super versatile since it works with pretty much every device. Definitely looks and feels way more expensive than it actually is.
Review: Love this keyboard! - The Keyboard comes with a lot of connectivity options, hardwired USB-C to USB-C, Bluetooth up to 3 devices and 2.4 radio receiver with a toggle to switch between connectivity modes + the keyboard is rechargeable. It is compact & that is one of the main reasons for buying this, the keys feel lightweight and precise, It is easy to setup as I said there are multiple connectivity options, but connecting to Win11 I needed to enabled advanced mode for the Bluetooth on my laptop so it can discover this keyboard. Very good looking and quality built. As to regarding the stability I think I shall know after a while of usage.

### ⭐⭐⭐⭐ Good chiclet keyboard with some miner drawbacks
*by O***R on February 6, 2025*

I had been using an older Apple bluetooth keyboard that used two AA batteries (see picture). Got tired of constantly replacing the rechargeable batteries so I switched to the Keychron B1. Overall, I'm quite satisfied with the keyboard. The typing experience is very similar to the Apple keyboard soI felt right at home after switching. The keyboard can be used in both wired and wireless mode. Using it in wireless mode the battery life has been excellent. So far I have charged it once on 11/27/24 and it still has a 37% charge, that's spending about 4-5 hours a day on the computer. One drawback/difference I had to get used to is that the 'bumps' or homing points on the 'F' and 'J' key are not very pronounced, quite delicate actually resulting in incorrect finger position at times and/or hunting for the home keys. Also, since the keyboard is designed for both Windows an Mac it does not have the dedicated Window/Mac symbols on the keys, rather just over/under text on the key - 'option/win' and 'command/alt'. Finally, the keyboard is not height adjustable. Again, coming from an Apple keyboard I was used to a steeper incline (18mm height in the back vs 12mm for the B1). For my purposes, I simply added some self-adhesive felt pads (see the picture) to increase the height. Overall, I think this keyboard offers a good combination of features and performance at a decent price point. Plus, the color scheme works well with the black Apple Magic Trackpad and a darker office table setup :-).
