Corsair K65 - Numpads are over-rated. But some action buttons on the left would be welcome. I bought an early iteration and wish I had the newer design on the keycaps. It's a bigger font that lets more light through, as opposed to basically the standard keycap font that is on mine.
Logitech G700 - I'm a big fan of the triple selection buttons. And I love the button that unlocks the mouse wheel. It's kind of like having a fidget spinner on your mouse. Mostly for scrolling webpages but I've enjoyed it in Cities: Skylines or when I'm scrolling through junk in my Pip-Boy in Fallout. This is a wireless mouse, but I haven't replaced the rechargeable batteries in it, just removed them as use the cable. I'm eyeing a premium mouse now.
Corsair HS70 SE - I'm a sucker for gold accents, and I needed something functional for RDO. I had a Logitech G430 and it was pretty bad. This is much better, but I still wish there was some more amplification on my voice. Although Discord does seem to have the best audio input signal capture. The wireless headset is non-negotiable for me now. The HS70 is a good compromise between features and price. I rarely use headphones for listening to music while on the go, but I have pods and another set of simple Audio Technica cans for that.
At work I just convinced them to buy us (CAD technicians) wired Corsair Harpoons. I like em, we had nothing but the basic iBuyPower mouse, and they were all breaking, so these are a vast improvement. I wish the mouse wheel tilted. I used to use a Logitech G600 for drafting, and I've considered just buying my own to keep .
And I do have a Logitech K400 which I very rarely use.
