Logitech G903 LIGHTSPEED Wireless Gaming Mouse W/ Hero 25K Sensor, PowerPlay Compatible, 140+ Hour with Rechargeable Battery and Lightsync RGB, Ambidextrous, 107G+10G optional, 25,600 DPI, Black

Southpaws rejoice. This is the one.
TLDR: I’ve been through a lot of mice. That’s because I’m wrong-handed with big mitts, and I’m always on the lookout for something that can compare to my dearly loved but deceased Logitech LX8. This Logitech G903 mouse is even better and hands-down the best mouse I’ve ever used.For southpaws like me, an ambidextrous mouse is about the best we can hope for. It’s a right-handed world, so it’s nice when a mouse isn’t specifically molded and curved for the right hand. This one is perfectly equal on all sides, but it’s more than that. It’s truly ambidextrous, and built with us lefty’s in mind.Size-wise, I wear XL men’s gloves, and this mouse fits my hand perfectly. Whether I want to use a full in-the-palm-of-my-hand grip or a fingertip ‘claw’ grip, it’s just right.The bottom of the mouse has six mouse feet, or skates. There’s a big one at the front and rear, as well as both sides, and it really glides well over my mouse pad. There’s even two smaller chevron-shaped skates surrounding the sensor, which I suspect also keeps dust out.The thumb wheel is outstanding. It works like any other, except that you can push a button right behind it, and it becomes freewheeling. Give it a good spin, and it’ll keep going up and down a page or an entire map of a game in the blink of an eye. Or you can use it the same as any other, albeit without any resistance. Push the button again, and you’re back to clicky resistance.There’s a DPI button, which I previously had no use for. Those buttons are usually on the bottom of a mouse, which makes them pretty useless. Out of sight, out of mind. But this one has two buttons right behind the mouse wheel resistance button and instantly changes the DPI settings up or down.What that does for me is make the mouse cursor faster or slower. There’s an on-screen pop-up when a change is made, and an LED light on the mouse shows one, two, or three lights that sort of indicate how many DPI, or how fast you’re going. I think this would be advantageous for some FPS or sniper games.The side buttons are perfect. You can use them all, on both sides, or you can use just the left or just the right and cover the others. It only takes two seconds to add or swap out because they and the covers are magnetic.When it’s all set up, the thumb buttons work exactly as I want them to. My thumbs naturally rest where they’re supposed to, on the solid part of the mouse, but it’s easy to rock them up slightly to activate either thumb button. With other mice, I was constantly clicking the buttons when I didn’t intend to; with this mouse, that’s not happening.There’s also a magnetic cover on the bottom of the mouse, which you push in hard to flip it out. From there, you can add or remove a 10-gram weight. I like a heavy mouse, so I’ve got it in.The last thing I absolutely LOVE is that although this is wireless (and has a great battery), you can plug it in and charge it while you’re using it. The cable it comes with is long, and you can keep the receiver plugged into it or use it to connect and charge the mouse. The only thing I don’t like about that is that it’s an old-fashioned USB-micro connector.Bottom line: Best mouse ever, and I’m thrilled. Well worth the money, and I hope this helps.

Top tier ambidexterous mouse!
Ambidexterous mice are such a specific niche of mouse that people don’t really look for. I’m in a unique situation where I’m almost completely ambidexterous and yet I also need wireless play and I need some great features. Too many mice that have features like Razer Hypershift or Logitech G-shift are too similar and even then don’t have a lot of buttons unless you’re like a G502. I am tired of the G502’s build quality and issues so I moved on. The G903 is the best next step. I get just as many buttons as the G502 but I have amazing battery life where I only need to charge once a week, and it feels so natural once you get the hang of the button layout. I use the right side upper button as a G-shfit modifier key to turn 4 buttons into 6+ and it’s so awesome. The mouse is also quite light in weight and you never really notice how heavy it is. I’m really in love with this mouse and how smooth it is over 2.4ghz connection. If you can snag this under $100 it’s absolutely worth it!

I am a right-handed person, the ambidextrous design bothers some people, but I find it comfortable.I use the thumb buttons for push-to-talk(PTT), one for in-game PTT, other for discord, etc, PTT.Don’t bother trying to use the buttons opposite to your thumb side(at least not for gaming), it’s a very awkward reach.Hyperscroll is very good for websites, the non-hyperscroll is very tactile and suitable for gaming.DPI changer is fine, but I don’t really use it often.No latency. Apparently, it’s supposed to be faster than wired, but honestly you can’t tell the difference.Sensors are technically supposed to be more accurate than the old model, not really humanly discernible considering how accurate sensors are nowadays.I’m an original G903 owner, so the rest of the review will be in comparison to the old version of the G903, which, in my opinion, was the best mouse.Snagged this for $150, $50 cheaper than what I paid for the original G903 when it first came out.Please take into account the fact that I have lighting disabled, it really adds nothing to the experience.I’m leaving this review because it arrived at half charge and after two weeks of non-stop usage, the battery finally went down to 3 percent. Charge is really fast too. After about a minute, the battery went to 20%. Amazing.Low battery indicator is not obnoxious like it is on the old G903. The old model would flash red and would be really distracting, the new model is more like a fade in and out really slowly, so it’s not annoying the crap out of me.Icons in the logitech software still don’t load properly, however, a reinstall which I am too lazy to do might fix it, regardless, everything is still functional in it. The UI doesn’t look like it was designed a decade ago, which is a plus I guess.Don’t get the powerplay mat, it’s pointless when the battery life is this good. Just charge it once a month while you’re watching a TV show episode, and you’re good. Off switch is pretty pointless considering it has a seamless auto-sleep function, only necessary for travelling.

Lo pedí una vez y le faltó una pieza yo creo que fue un error de empaquetado, pero el mouse se veía excelente, así que lo pedí de nuevo y ahora si venía perfecto, ya lo probé y funciona muyy bien, así que satisfecha con el producto 🙂

El mouse entregado es uno claramente usado, y ni si quiera para limpiarlo un poco para entregarlo y fingir que no es así. Lo probaré un poco y si no lo devolveré inmediatamente.
