Logitech has done an outstanding job manufacturing a wireless competitive gaming mouse. I personally will never be sold on the idea of a wireless mouse being better than a wired one just because of signal interference alone, this does not detract from the fact that this mouse is indeed a dam good mouse even for fast pace FPS shooters. I will try to go in order writing my review of this mouse from opening to playing with it.*Packaging*For a $150 mouse I expected more from the packaging however I do understand that maybe Logitech wanted to keep things simple. There is no wow factor here just a simple small box wrapped in plastic. Looking at it from the outside you wouldn't be able to tell this thing costs$150.*Opening*So once I got into the box that looks as though the contents of it didn't cost $150, I was once again taken aback. Reason being that the mouse was just sitting there unwrapped. The reason this kinda surprised me was because I had to make sure that I didn't accidentally order a used mouse. Nothing against used electronics but I generally stay away from them because they could potentially have unseen underlying issues, however Amazon and their generous return policy has restored some of my confidence in buying them but I did not want to go that route with this mouse at this price point. The mouse did have tape on the underside once I lifted it from its cradle but again I did double check to make sure that it wasn't a used product. I removed the tape from the underside and checked the mouse skates for any signs of scratches and everything was cool.*Package Contents*The package contained what you'd expect. The mouse, a wireless dongle, and a cord all wrapped and in good condition. One thing that concerned me that I wasn't sure about was whether or not the buttons on the right side of the mouse were preinstalled and to my relief they weren't. The reason I say this is because I prefer not to disassemble my electronics if I don't have to, if you have to then you gotta do what you gotta do but I work in maintenance and repeatedly taking something apart and putting it back together causes excessive wear and damage and I'd prefer keeping my $150 mouse in pristine condition other than normal wear and tear.*The Mouse*The mouse itself felt great, it felt solid and sound. The shell was sturdy I'm a heavy handed individual and I was comfortable applying normal pressures from my hands to the mouse with fear or it being damaged or broken. The mouse slides gracefully across the mouse pad out of the box so you won't encounter issues there, I would've preferred they used the mouse skates Razer has been using on their largest mice but it is what it is I ordered some Hyperglides to replace them.*Installation*So the mouse is plug & play, I already had G Hub installed and the software recognized the hardware no problem. I didn't have to update any firmware or anything so that was cool I just plugged the dongle into the computer and turned the mouse on from the bottom and it was good to go.*The feels*So I have large hands and going into this I expected it to be small for my hands and I was correct. I use somewhat of a palm claw hybrid and I found that I had some empty space between my hand and the mouse itself which is kinda like a dead zone and could cause slop when making fast movements. Like I said I anticipated this going in so I can't say I'm disappointed. The side buttons are nice as well as far as where they are positioned and how they feel when you press them, they're very responsive. My only gripe would really be to move them back a little but I attribute that to the size of the mouse itself if the mouse was a little larger they'd naturally be further back. The button position in relation to the size of the mouse is fine and about where you'd expect them to be. The two main mouse buttons feel pretty good as well the clicks sound good and feel equally as good I had no double click issues or indications thereof. One thing to really look out for are people buying this product used from someone else who had the double click issue and sending it back then someone else buys the mouse again with the same problem and all of a sudden a lot of people end up sharing the same mouse with the same issue leaving the same review complaining about the same problem. I've encountered no double click issue so far. The weight of the mouse itself is great as well it feels really balanced not too light but not too heavy.*Tracking*So this is where the rubber meets the road, I wanted to test just how good this mouse is and if it's as good as they say it is. I tried this thing out not in Microsoft word or nothing like that I went straight to Apex Legends and COD. I went into G Hub to check my configurations and much to my surprise I didn't have to do anything another good thing about G Hub is that your settings apply universally to all Logitech mice so because I had profiles set up for one mouse they assumed it'd be the same for this one so that was a good surprise. The mouse tracked very well I have to admit I was impressed for a wireless mouse that didn't fit my hands that well I performed amicably and even was champion a few games and I'm not one to argue with results. The mouse tracked even my most minute movements without skipping a beat.*Conclusion*I was on the fence about even picking up a wireless mouse because I wasn't sure if the technology was really ready for competitive gaming but it has come a long way. My only real issue with wireless is the batteries, no matter how good the battery may be eventually it will wear out and turn your wireless mouse back into a wired one Logitech could circumvent this by making the battery removable but they'd sell less mice in doing so. Which leads me to the reason I chose Logitech over Razer because I've had to trash a wireless mouse once already in the past granted the technology back then isn't what it was today. I'll hold on to the mouse because I like it and it performs it will be the one in the arsenal. I've attached some photos of the mouse alongside some more other popular mice in the game for size comparison. Enjoy.
