@SarraceniaWilds This little guy is the one I used for years and years. I have since switched to a slightly larger logitech, mostly because wireless is easier with my desktop at work.
(they made a smaller one at the time, but even for someone with fairly small hands it wouldn't have been comfortable to use all of the time)
I had this one and loved it so much. Tiny little bright red puck shaped thing. I wish they still sold them

Smol Mouse is Soft and Tender
Also AI mouse? Silly little mouse! That is as silly as Peak Dot Com Bubble where you could get a keyboard with a Pizza Key that launched your web browser and went to Domino's Pizza website when you pressed it.

@SarraceniaWilds My phone's default lens is obviously quite a wide angle - that picture of the netbook mouse in front of the Bluetooth mouse makes it look much larger than it really is...
Just measured - it's 6 x 4.5 x 1cm - so like the pink mouse in the first post but slimmer.
