I purchased WOBKEY Rainy 75 Standard Aluminum 75% Hotswap Wireless A-RGB Mechanical Keyboard. The metal frame of the keyboard is sturdy and feels nice. The violet keys are great and have the best feel of any switch type I've used before (I had blues previously). The RGB works well (I wish there was a white color option though). The battery I'd estimate I have to charge every 2 weeks or so. I'm using the non-Bluetooth wireless option. I'm very happy with the keyboard, especially for the price, because I know that keyboards can get really expensive.
