I have the Logitech g903 w/ the induction charging mousepad as well. It is amazing. It is as responsive as a USB mouse with the freedom of being wireless and there is no need for batteries. Drivers work flawlessly. This gives me a lot of freedom for positioning the mouse on the desk wherever I want regardless of where the stick, throttle, kb, mousepad, and other desk items are located. I use VR (rift cv1) so I cant always see the desk and need to be able to pull everything into hands reach all at once. This is probably the best mouse on the market. my last Logitech mouse lasted over 10 years, so when you consider its cost/durability it is also probably the cheapest mouse.
I run a mechanical keyboard, Corsair k95 RGB - I do not recommend this KB.
I have a Razer mechanical Black Widow Stealth keyboard as well - I do not recommend this KB either. The Razer KB has a dead left alt key and a terrible cloud based driver-profile thing. The k95 rgb keyboard has burned out LEDs and a terrible onboard profile and icue driver abomination thing. both keyboards are overpriced garbage. Do _not_ buy their products.
Try and find a mechanical keyboard that does not have backlighting as that stuff is highly prone to failure. Saves $ too.
