Went on spree recently. We've had cheap mice for ages. With the lockdown and sales bought a few. There 5 of us using PCs and laptops. So mice get swapped about a fair bit. Have a few oem mice...
G203, works well. Shape is too flat.
G403, like this. Wish the shape was higher. Probably favourite shape of the Logitechs I have. Like the sensitively the best.
G903, like this, wish the adapter was internal like the pro. But I like shape. Tad big.
Logitech ProWireless, like this. Sensitivity is just alright but holding the USB adapter internally magnetically is so handy. I use it for work laptop. The shape isn't perfect the hump is too middle for me. Prefer it more pear shaped. But use it a lot.
Mx518 hate this. Seems slow by default only works if you open the app. it's slippy and weird shape. No one likes this here. I'll be selling this one.
Our favourite mouse is a cheap advent large mouse. It's like an offset pear. They changed the model and the new has cheaper plastic and sharp edges. Threw that out.
Have had razer in the past. Probably the early models. The shape was too weird for me.
