The grip is comfortable and it glides nicely. All buttons are programmable, which is what I really wanted. Lots of sensitivity ranges. It took me a while to figure out how to program the other buttons, but they are all programmable. LED lighting can be modified and multiple colours are interchangeable.

Left click failed in 2 months. Triple clicks when its not supposed to. Won't hold while while left button is clicked and held.

I loved this mouse, but I have encountered this problem on other LG mouses in the past. I hoped for the best, that it would last but was very disappointed. Tried to fix it using online guides for this mouse specifically, to no avail. Sadly, I'm going to buy another one cause I love its mouse functions and capabilities, but getting warranty this time. If you choose this mouse, get the warranty. If you're not particular about mouses, avoid it!

I can only assume I either got lucky when i got my mouse (about 2 years ago now) or they are putting a lot of pressure on the mouse buttons to have them break. I also have the G510 keyboard and so they sync up great together. The added weights to the mouse add such a nice feel to it. I use all the weights in mine as it feels much better for me, also if you play simulators (like truck sims) and your wheel and shifters knock around and can jar your mouse if its a lightweight product, but the added weight keep it in place. 3 profiles can be used for various settings, personally I only use 2 (shooters and literally every other game) until I find a game that may need the 3rd.

The only weakness Ive found with this mouse was the slippery wheel. If they had put a rubberized grip on it so it can roll easier BUT I have used a q-tip and applied a bit of plasti-dip on my mouse wheel and now its flawless.

This is one of he best mice I have used so far for pc gaming and especially fps games as the extra buttons on the mouse make it easier for harder to reach keys. Highly recommend

Great feel, felt natural to use the day i took it out of the box. adjusted the weights so that it mimicked the weight of my old mouse and immediately started playing.

I'm at about 8 months of use and the left clicker is starting to randomly double click on me, it's fine one minute, and rapidly double clicking the next

It's great while it works, but don't get too attached to it

Great looking mouse

Left click is faulty. Left clicking results in a double click about 10 to 20% of the time. Issue showed up few months after purchase.

Don't recommend as others seem to have the same issue. From research on the net, it seems like a hardware issue.

Comfortable grip, and a great mouse to use - when it works.

Extremely fragile - the right click began to give out after roughly 8 months of regular use. It fails to hold a click and this makes it borderline useless for gaming or just about anything.

Stay away from this mouse, and if you DO decide to buy it - get the warranty. It WILL break on you.

Have used the g502 platform for years now over 2 separate mice. Have not had any major issues with either.

- Comfortable and Good Rubber Grip - Good Programmable Buttons and Design - Optional Mouse Weight - Control Scroll Wheel Behaviour - RGB Lights

- Similar to other people's experiences, my Left Mouse Button became faulty after about 4-5 months. This makes it impossible to do 'Click and Drag'. - My Right Mouse Button also followed a month after the Left Button Button became faulty. - Unfit for people with big thumbs - you might accidentally click the Side Buttons (Mouse Forward, Backward & DPI Shift) which may cause unintended actions, especially if buttons are assigned while gaming.

Not bad for my first Logitech Mouse. However, the #1 and Critical Issue about the Click Buttons is a killjoy, mostly for gaming.

Light click sometimes wont hold anymore, the middle click is not good

will not buy this again, I would recommend you dont buy this

The Left Click on the mouse, like every other review on here, has become unusable within a few months of owning! Very surprised and disappointed in this product!

Would recommend to stay away from this product.

Great function key layout, highly programmable

Switch failed; Swift switch button a bit heavy

Great mouse but need to last for the price.
