The mouse I currently use is the Logitech M705.
Of all the Logitech mice I've used, its by far the most comfortable mouse and has multiple customizable buttons.
I'd say its rather affordable and has a battery life of up to 3 years which is pretty insane.

I also have that mouse and it's nice but ffs the battery is ****. It literally lasts about two days before you have to charge.
As far as connection problems it comes with an extender so you can get the dongle closer. Never had reliability or delays with it.
