Awesome gaming mouse if you like heavy mice. Comfortable, accurate, and a long battery life. If you are a gamer that plays on low sensitivity and prefers a lightweight mouse, i wouldn't recommend this product. You CAN remove the weights from the mouse, but it's still not going to be as light as a logitech gaming mouse. I personally like my gaming mice to be on the heavier side, and the M65 Ultra Wireless is easily my favorite mouse. It's easily a 10/10 for me.

Very nice mouse. Fits great in my hand. The custom weights allow you to adjust according to your liking. Which is great. Only con I have is the RGB lighting is minimal. But thats to increase battery life. So I can accept it. Still 5 stars for me

The Corsair-M65 Wireless Optical Gaming Mouse is the BEST mouse I've ever purchased. It's design, adjustable weights and programmable buttons makes for balanced handling and fast, smooth, accurate gameplay. Superior wheel response, a "sniper" button and custom lighting are bonuses. Simply connect to your computer USB port for programming buttons, firmware updates and recharging. That's right, it recharges in minutes. Bought this baby 1 month ago, never switched it off (sleep mode). Battery medium notification popped up in my toolbar 4 days ago. Connected USB (still functional while charging) and in just a few minutes, fully charged! This mouse is awesome!

excellent build quality and response time. running it with a corsair k100 air off of only one receiver. battery life is insane

This is my first gaming specific mouse. I was instantly pleased with the build quality and weight. It glides and tracks seamlessly and is really accurate out of the box. Just the right amount of buttons to program and not too overwhelming. The option to adjust weights is cool if you notice those subtle differences. My only issue is that i wish there were more lighted areas rather than just the logo in the back. I probably should have noticed this before purchasing, however. Quality mouse, reasonable price. Worth it.

Great for gaming or normal use. Nice weight comfortable and really good size gor big hands 10/10

This mouse is smooth, responsive, and comfortable. I notice zero latency even being wireless. You will not be disappointed if you buy this mouse!

Overall, I've really loved this mouse. It's been great for the past two years and 12 days I've owned it. However, just 12 days after the Corsair warranty period, it conveniently decided to break in the middle of a gaming session. Really unfortunate.

I've been using a Logitech wired mouse for years that I really liked, but it was finally time to retire it, and this Corsair matched my new keyboard. I'm extremely impressed. I was worried about latency, but it's non-existent. The configuration options are fantastic. And ultimately, it just feels great in the hand.

I was very skeptical buying this product. Such a high price for a mouse when I could get a wired version for about $50 cheaper. This mouse is amazing. Jam packed with more features then it’s wired brother. I love not having a cable not anywhere messing with the movement of the mouse. And being able to use either the new Slipstream dongle or Bluetooth is a very nice to have. Very fast, lightweight, and perfect for my gaming.

Material is okay, doesn't feel too cheap. It's a little small for my hands

So smooth and comfortable! I love gaming with it and it stays charged for a long time.

The M65 has always been a favorite of mine and this wireless version is the best. I love the weight by itself without the included weights, the wireless is flawless, the button placement is perfect right where my finger can press them, and it is so smooth on my HyperX mouse pad.

The best fittinf mouse for my large hands. I dont have long fingers but they are pretty wide and this mouse feels so nice! The weight isnt bad on it, i dont have any of the weights it comes with it added, and it glides so nice.

Lasting a longggg time! It’s been about 2 - 3 weeks now and still above 80% . Its amazing for what technology can be! Wireless is also amazing , haven’t noticed the difference between wired vs wireless . More freedom with my wireless mouse!

Overall its a good mouse. The price was not that good it was marked for 89.99 but for some reason it came up to 130.00. But that was more of best buys problem. I like the weights and it has a good response times. I dont like the access to the weights.

Works great! We use it all the time, almost never needs charging. Much better than a cable gaming mouse.

This mouse has far exceeded my expectations for a gaming mouse. The weight system alone is very cool. You can have a really light mouse or by adding the weights you can really personalize the feel of the mouse! I really love this thing because it feels so comfortable in my hand!

Even still with the including weights, feels super ligh weight yet it feels hefty which is something that I like in a mouse. That weight to it allows me to move it more precisely when gaming and when editing audio. Size is average. I like large mice but its just hard to find them like that in this category. This one feels comfortable in both claw and full hand position. Scrolling wheel feels solid and the switches are very clicky. This ine in particular has optical switches which is a must for me as they are supposed to be more durable than mechanical. Mexhanical switches are more prone to the double click issue which is the reason I bought this one.

The Mouse itself is nice. Good sturdy feel to it. The 3 stars is because the screws that it comes with to secure the weights are cheap and 2 of the 3 snapped in half with very little tightning effort involved. The other reason for the 3 stars is because of the Icue software that has to be downloaded for the extra functions of the mouse. The software program repeatedly hijacks the lights to my motherboard and fans including anything else with ARBG lights. Other than that the mouse is great and the battery life last every bit of the advertised 40+ hours. For the price though its definitely worth it. I still prefer it over my Razer Naga Pro.
