Review: Viper Ultimate WINS vs. Logitech G903 - I've owned both, and wanted to share some insights that I would have liked to have known before laying down this kind of cash for a mouse: Right off the bat, I need to say that the G903 is an excellent mouse but has a massive, fatal flaw: Logitech refuses to source an alternative to the frequently defective switches in its primary buttons. If you google 'G903 double click issues,' you will find that these switches fail at an alarming rate. This happened to me, after around 14mos for the original, 10mos. for the replacement under warranty. Logitech refused to replace the replacement. I consider this failure rate completely unacceptable for a "premium" mouse. My last mouse is 5+ years old and still going strong; I'm only switching because I wanted to go wireless. Personally, I will likely not trust Logitech for some time. If you're willing to take the risk, see below for a comparison. Performance Both of these mice are incredibly responsive. I would be hard pressed to tell the difference between wired and wireless modes on either mouse. Both sensors are excellent and perform well on all surfaces. Both of the mice have 5 steps of mouse sensitivity that can be individually modified by the user in the mouse software. I love this. The G903 has two dedicated buttons on the top of the mouse to move up and down between these sensitivity steps, which is much more convenient than the Viper's single button located on the underside of the mouse. I assigned one of the Viper's side buttons for this, but it's not as convenient. Ergonomics: Both of these mice are ambidextrous. (I'm left handed.) The G903's larger size and rounder shape is probably best suited for a palm grip, but I use a claw grip and was totally fine. The main thing is the G903 is a large mouse. People with smaller hands will likely find this mouse cumbersome. I slightly prefer the G903's side buttons, which protrude further than the Viper's which makes them a little easier to click, but this will be very subjective. The Viper is a little flatter, a little narrower, and a little shorter, and the form factor a little better for my medium sized hands. It's also a lot lighter. The G903 does have customizable weights, although I don't really see the necessity of this. Battery Life: The Viper is rated to have a much longer battery life than the G903, but I found myself charging both of these mice every 3-5 days or so, depending on computer use. The Viper does have the option to come with a dock, which I find convenient. However, the USB connection, though standard, is hidden in an extremely narrow cutout that most generic cables will not fit in. The G903 has a mousepad that lets you charge as you play, which is a cool idea, but it's expensive and really, as long as a mouse lasts a full day it's not that hard to charge at night. Wow, that was a long review. Never done one that long before. I just spent a ton of time researching and a ton of money buying these two mice, so thought I'd try to share some of that.
Review: The First Razer Product I Like! - I have purchased Razer mice in the past and have never liked the way they felt in my hand. This mouse however, feels great and I love it. I bought this to replace my Glorious Model O mouse because I wanted to go wireless. It's amazing that this wireless mouse is only about 6 grams heavier than the Model O and it doesn't even need to have the hexagonal pattern on the case to remove weight. I spend a lot of time in first-person shooters like Rainbow Six Siege and Battlefield when I'm not at my desktop doing normal daily web browsing and email reading. Here are some pros: - Feels very light, especially for a wireless mouse. - I don't sense any delay, even after I leave it sitting for a while. - It's very convenient to have a power button on the bottom of the mouse, and to have a charging dock to sit it on when not in use. - The button clicks are very satisfying - good sound, good force needed (not too much or too little for my taste). - Lighting is tasteful and not too overdone. - The finish on the mouse is nice to the touch - grippy on the sides, and smoothly textured elsewhere. - The side buttons are well-placed for my thumb. Others have been a little too far forward for me. - The battery life seems great. I am part-way through my fifth day of use and the battery is at 51%. I have been using it to play games every day for at least 3-5 hours per night plus regular Desktop duties for at least an hour each day as well. I have not recharged it yet and I turn off the power at the end of each day when I am done with the mouse for the night. - The Synapse software is much better than I expected and has not crashed for me once. It's pretty easy to understand and laid out fairly well. It's great that it will change profiles for me automatically based on the games I start up, then go back to my "desktop" profile after I close the game. Here are some cons (for mouse, and Synapse software): - I miss the extra button on top of the mouse that my Model O had. I wish this mouse had that extra button near the scroll wheel. I have had to use one of the right-side buttons instead. Although the right-side buttons are not as easy to press for me (since I'm a right-handed user) I'm getting used to them for desktop use. - I find the lighting options a bit confusing with regards to the "Quick" effects and the "Advanced" effects in the Synapse software. Mostly, it's frustrating that only the Quick effects are stored on the mouse with the profiles and not the Advanced effects. I think this means that if you want to use any of the Advanced effects, they will not be saved on the mouse and I'm not sure if they can be tied to games like the other profiles. Before I can really fault the mouse or software for this one, I suppose I need to learn how to use it more. Either way, I wish it were a little simpler to understand for first-time Synapse users like me. - I wish the mouse feet were "slipperier". Compared to my Model O mouse, this mouse does not move across my cloth mouse mat as easily. My no means is it "not" slippery, but it was noticeably less slippery when I was swapping them out. Now that I have not used my Model O for about 5 days, I don't notice it any more or have any issues moving the mouse, but it would be nice to know that it was at least as free to move as the Model O. This might turn into a plus as I get used to it because it may give me a little more "control". To summarize, I love this mouse! It's been great to use so far and I'm very glad I switched back to this wireless option. Lot's to like here and the software (despite some shortcomings) is much better than I expected and seems mostly mature and works well.

### ⭐⭐⭐⭐⭐ Review
*by J***. on September 15, 2024*

Lo llevo usando un tiempo y es increíble, lo que más me gusta es el diseño creo que es de los mejores en el mercado siendo minimalista, perfecto incluso si eres zurdo y ligero. Los únicos 2 peros para mi es la duración de la batería no siento que sea demasiada, si no te gusta la iluminación podrás desactivarla y ahorrar batería, lo puedes usar cableado o inalámbrico aunque el otro punto que no me gusta es que usa micro usb y no usb C además de que al conectarlo es un poco incómodo ya que está como que metido pero al final esto también ayuda en la estética, el software te aparece automáticamente al conectarlo a tu PC para que lo puedas instalar y no busques en internet lo cual se agradece, no he tenido fallas ni nada por el estilo, por el precio me parece que está muy bien al final es un mouse de gama alta que a pesar de tener ya sus años en 2024 sigue siendo mejor que muchos más modernos.
