Logitech G502 Lightspeed

The mouse half of the same receiver as the keyboard, and the one I keep going back to after trying lighter things.

Why I like it

The free-spinning wheel is the feature I would not give up. Flick it and it runs for several seconds, which takes a 2000-line file or a long diff from a scroll to a gesture. Clicking the tension release turns it back into a notched wheel for precision work. Most mice make you choose one behaviour at purchase; this one puts the choice under your finger.

Eleven programmable buttons is more than anyone needs and exactly right for a few things: a thumb button bound to back, one to a push-to-talk key, and the sniper button as a temporary DPI drop. The rest I leave alone, because a binding you have to remember is a binding you will get wrong under pressure.

Lightspeed is the same protocol and the same receiver as the G915 TKL, which is the practical argument for buying the pair: one dongle, one charging habit, no Bluetooth pairing dance when you switch the machine on.

The honest caveat

It is heavy, and the weight is not incidental. This is a tall, wide, right-hand-only shape built for a palm grip. If you use a claw or fingertip grip, or your hands are small, the shape will fight you and no amount of sensor quality fixes that. Try the shape before the spec sheet: the hand decides this one.

Who it's for

• Palm grippers with medium to large hands who scroll through a lot of text.
• Anyone already on a Lightspeed keyboard who wants one receiver for both.
• Not for you if you want a light mouse, a symmetrical one, or a left-handed one.
