This colorway comes with an E-white Aluminum top case while all the other colorways come with a Polycarbonate top case. That's the reason it costs more than the others.
A standard sized, widely available LiPo battery is required for Bluetooth editions but it's not included with the kit.
Stabilisers are not included with these kits, you need to purchase them separately. Aurora R2 kits have 1.2 mm PCB by default, WS Stabs 1.2mm fit them perfectly, no need for washers or shims. Since BODO and Iceland have more hotswap sockets for various kinds of splits, normal washers or shims won't sit properly.
People who work here are really helpful and go above and beyond with customer service. Highly recommend.
The Aurora R2 is a fantastic keyboard, it features a ton of it features a ton of customizability including a top accent piece, Bluetooth compatibility if you purchase the correct PCB and feel plus sound is amazing.
The downsindes is that it does feel like a plastic board and it does not come with stabilisers in the kit but if you don't like that you can purchase the extra top aluminium plate and brass weight to help the weight.
