It’s a large (5.2 x 3.0 x 1.6 inches), matte black, right-handed, ergonomic mouse with a curved thumb rest and textured grips weighing 114 grams (4.3 ounces) with two RGB light zones (one of them is the Logitech G logo) and a HERO 16K sensor. Also in the box you get a cable, a little storage box where you’ll find the weights and usb dongle. The dongle fits on the end of the usb cable acting like an extention so it can sit closer to the mouse offerening better connectivity. This is great as I’ve hidden the computer under the desk and found my old MX Master lost some of its reach compared to before. There is a compartment under the power play disc where you can store the usb dongle if you want to take it to other locations.

I’ve noticed there doesn’t seem to be any spare parts available from the Logitech website, so you’ll have to source third party if anything does go wrong and you’re out of warranty.

• The weight is customizable. There is a weight system on the bottom, so If you prefer a heavier mouse or want to weigh the mouse more to one side or the other, you can add an additional 16g via two 4g weights and four 2g weights.
• The large design of the mouse may be uncomfortable for people with small hands.

Tip: To get to the weight system just pull the edge away from the mouse under the thumb rest. It’s only magnetic so should come away easily.

At the expense of adding some weight, the G502 Lightspeed is compatible with Logitech Powerplay charging mouse pad, which plugs into your PC via USB Type-A, so you don’t need to worry about charging it.

• Without the Powerplay Mat Logitech claims 48 hours of use with default lighting and 60 with no lighting.
• It does charge quickly, up from nearly empty to 100% inside 90 minutes.
• By default the button under the scroll lock will light up the bars on the left of the mouse and the G logo which give you a quick indication of how much juice you’ve got left. Green (good), Orange (mid range) and Red (low).
• The low battery warning comes on when the battery hits 15% the RGB light on the G Logo with turn red with a breathing effect. You can also always load the G Hub software, where it will display the remaining battery percentage.

Logitech’s G Hub software is where you have the ability to reprogram the buttons, customize RGB and the 100 – 25,600 DPI sensitivity options. (Originally DPI max was 16,000, make sure to get latest update to get the full 25,600) You can even create different profiles and have your customizations ready for different games or for productivity. You can also record macros, commands or actions and assign them to any button you want. You can use actions with the likes of Overwolf, Discord or OBS.

• If your short of room then a higher DPI will help immensely, moving the pointer across the screen faster with little movement or lower the DPI for precise accuracy for games or editing images.
• One thing that baffles me is, there’s no obvious way to set the RGB lights to turn off with inactivity or when you turn your computer off or to sleep. It’s in the keyboard settings but not the mouse, surely this could be corrected with a software update?

Tip: To use G Shift you have to assign a button, go to profile configuration > assignments > system. Once assigned you have to press and hold your G Shift button to activate it. Think of it like the shift key on your keyboard.

Tip: I use the G6, ‘Shoot’ thumb button to activate the G Shift.

Tip: When I installed G hub I initially ticked the ‘Make my experience better’ options, however after a short while i found that this caused the G hub software to fail and just display a black box. To solve this I had to uninstall and then reinstall, this time not ticking the boxes ‘Share data’ or ‘Send error logs’. I haven’t had the problem occur since.
