It's just a Proteus Core, but wireless. Wait... it's a PROTEUS CORE, but WIRELESS!!!
Color: Black, Style: Wireless, Pattern Name: Mouse
I've been using a Logitech G502 Proteus Core for a couple of years, and I've been wanting a wireless mouse for ages however, I had been hesitant to switch to anything else because I loved that G502 Proteus Core. Then, this mouse came out. I knew it was time to upgrade. I get a mouse that looks, feels and performs identically to my Proteus Core. No, scratch that, BETTER than my Proteus Core. Except now no more wire wrangling. No more wire catching on the edge of a table or needing to tape it down. Except the sensor is faster and better than my G502PC, and the wireless mouse is somehow LIGHTER than the wired version. What kind of space age magic is this!? When I got it at first, I was actually a little disappointed. I had been excited for this new, fancy mouse that was going to step my game up. But then I got it and it just felt exactly like my old one. It felt like nothing has changed. The wait to use it came to a somewhat anticlimactic end. But then I thought about it and realized..... IT FEELS EXACTLY LIKE MY OLD ONE. I got literally exactly what I loved before, but this time with RGB lighting and no cord! What had I expected? I got literally exactly what I wanted, and it felt like home. And the battery life, of my goodness, the battery life. I've been using this mouse since mid Early/mid-May. I probably use my mouse for about 1 to 4 hours a day, sometimes every other day depending on schedule. I charged this mouse to 100% on my first day of ownership. I haven't charged it since, and my battery currently reads 64%. Incredible. Over a month of regular and consistent use, with lighting on (at about 60-75% brightness, purple) and I haven't even gotten it to half charge. That tells me I've probably got another month or so of battery life to go! I have been BEYOND satisfied with this mouse. I only had one minor hiccup. Initially I put the wireless receiver in the rear of the tower, straight into the motherboard's primary USB 3 port. Unfortunately, I noticed that I would get occasional stuttering and hitching with the mouse cursor. After a bit I noticed that it only happened when my cell phone was on my computer desk in front of my mousepad. I relocated the receiver to the USB3 slot on my Corsair K60 keyboard, problem solved. I haven't had one stutter or hitch since. I think my cell phone's WiFi signal was causing some form of interference. I could reproduce the problem with my cell phone location every time, so I'm confident in what the issue was. BEYOND satisfied with this product. If you have ever used any of the Logitech G502 line - or mice of a similar shape - this product is an absolute NO BRAINER purchase.

It's a good product but not quite a grand slam..
Color: Black, Style: Wireless, Pattern Name: Mouse
I've tried 15+ different mice in the last few years. It would be a bigger number if I wanted to collect them, but I mainly just try to buy the best small to medium-ish ultralight mice in search of my endgame. Won't buy a mouse without seeing reviews first anymore. However, I did main the old wired G502 for a long time before I became a snob. I still like the G502 shape, scroll wheel, and button layout very much despite the fact that it's not going to help me get high scores in aim trainers. The disadvantages caused by the weight and shape are somewhat, but not totally, made up for by the added functionality of the extra buttons, which are also fantastic for productivity. This is an overall solid product with only a few minor flaws that kept me from giving it a perfect score. The good: 1. Weight is noticeably reduced compared to the wired version. 2. The button layout every G502 fan fawns over is now on a wireless mouse. And it's genuinely a great button layout. 3. It's wireless, obviously. 4. Top-tier sensor. 5. Excellent battery life. 6. Infinite scroll wheel go brrrrr The bad: 1. Standard black teflon mouse feet. Not the worst I've seen, but Logitech does have a reputation for putting sh*tty feet on great mice. They at least improved this on the Superlight, but even those were still too thin. These aren't bad, but they could be better. 2. Click feel is substantially worse compared to the old G502. Switches are clearly not the same. Honestly would've been tempted to give this mouse 5 stars if it weren't for the clicks. They aren't heavy and ultra tactile like they were before. They're light and standard-feeling now, which isn't a deal-breaker by any stretch, but it's disappointing. 3. Price. You have to get this thing for less than $100 or it simply isn't worth it. It's a step up from the wired G502 but not to the point of it being worth 3 times as much. Even at a $95 sale price, that's still pushing it. Summary: you're sacrificing click feel and money to improve weight, obtain a nicer scroll wheel, and rid yourself of the atrocity that is the original G502 cable. You're also getting great battery life and excellent, low-latency wireless tech. It's a good mouse, but it's hard to say it's worth triple the amount of its predecessor, especially if you can replace mouse cables. Do not pay more than $100 for this mouse.

The best mouse is the best mouse
Color: Black, Style: Wireless, Pattern Name: Mouse
I've used the wired in the past and it was my favorite mouse and after using an ASUS wireless mouse for the last 2 years I decided to go back to the Logi G502 only the wireless version this time. Connectivity is great. Disappointed that it doesn't use USB-C to charge the mouse itself, but whatever. This thing is so great and more comfortable than the last mouse I was using. That's a win All I'm saying is it's great to have this mouse again because it's hard to argue that this is the best mouse for gaming. I can't comment on battery life as I just received it but from the rest of the reviews, its has great battery life. But upon immediate use, I just can't recommend this mouse enough!!!

As advertised. Logitech, best mouse for your hard-earned cheddar! It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse. So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it! 😉
