Well, I have had this mouse for 1 year. I have made good use of it, I haven't fought with it because I bought it for around 80 euros. I only hit it once, but it didn't get offended and continued to work (I didn't break it, as you can see in the photos). Unfortunately, after a year, I stopped using the mouse because I had to constantly change the battery (every 5 to 7 days), so I bought another one. While I didn't use it for a week, I decided to go back to it to see the difference with the other mouse. Unfortunately, for my bad luck, the first one stopped working from the thumb buttons (button 5) just because it smoked. It is a general issue with this mouse (the same in some forums), so for me, it is now a useless mouse since I bought it for FPS games. While I had it, it was commendable, especially with AAA batteries, it was very lightweight (and with AA batteries, it was relatively light compared to other mice, search the internet for more information), but after the unfortunate incident with mouse button 5, my good opinion of the mouse changed. For the money I bought it, the fact that it presented a defect in one year is unacceptable, so I do not recommend it.
P.S: BE CAREFUL BECAUSE DISCONNECTIONS MAY OCCUR BECAUSE THE MOUSE DONGLE IS NOT VERY GOOD AND IT HAS ISSUES WITH USB 2.0, 3.1, 3.2 PORTS. 3.0 IS THE SOLUTION, OTHERWISE USE AN EXTENDER.

UPDATE(2): I've had it for 2.5 years, it still works, but I don't like the Bluetooth connection. It's only worth it with 2.4 GHz, and it has scroll jumps. They say you have to blow between the scroll wheel, but it only improves it slightly for a day and then it continues. Otherwise, it's still great, but I'm thinking of getting the Viper Ultimate, V2 Pro, or Razer Naga v2 pro because I have a claw grip and small hands.

UPDATE(1): It started jumping when scrolling, and usually, this happens with all Razer mice.

I've had it for about 1.5 months now,
It works fine, 950 hours with Bluetooth + lithium battery for everyday use
Otherwise, 450 hours with a lithium battery and 2.4 GHz USB dongle for non-disconnecting gaming
It may have a problem with Bluetooth only, where it disconnects and enters pairing mode
It may be an issue with my mouse or because I have an old laptop
And hopefully, it won't become problematic like the old Deathadder Chroma with double left-click in a few months..

Conclusion: 950 hours with one battery is UNBELIEVABLE.

The Razer Orochi V2 is a truly great mouse, especially for people who want something with a long-lasting battery that will last for MANY days, an ideal design for all grips (depending on their palm), excellent wireless connectivity, and addictive switches. It is also what a former Logitech G305 user needs, as it offers a refreshed shape, better battery life, improved optical sensor, better switches, and overall a "proper" remake of their mouse. This new gaming mouse is Razer's approach to something powerful, portable, with fantastic performance, and at an affordable price compared to the rest of the high-end wireless market.

The first Orochi, released a few years ago, was a classic laptop mouse, without many gaming features and performance that would satisfy demanding users. It was also incredibly overpriced, making it a bad purchase for gamers and non-gamers alike.

I own many wireless peripherals such as the top ones in the market, Logitech G PRO X, Razer Viper Ultimate, and Razer Deathadder V2 Pro. This Orochi V2 is now my new main/daily gaming mouse, and it could be yours too. Razer has released something that is competitive, affordable for the average user, packed with features, and has nothing to fear compared to other wireless mice on the market today or even tomorrow.

With a launch price of €69, it comes with a Lithium AA battery that keeps the mouse alive for 950 hours/40 days of continuous use with Bluetooth connection and 425 hours/18 days of continuous use with the 2.4GHz dongle. This means that if you use the mouse for 8 hours a day, it will last you 118 days with Bluetooth and 53 days with the dongle.

The mouse weighs approximately 58 grams without a battery, 72 grams with an AA battery, and 68.5 grams with an AAA battery. It has an ideal weight, especially compared to the market.

It can be connected via Bluetooth for use with devices that support Bluetooth, but I do not recommend it for gaming (too much delay for my taste), and with a USB dongle, you will experience the same or even less delay compared to a wired mouse.

I find its shape more comfortable than the Viper Mini and Deathadder Mini. It is suitable for claw grip on medium/small palms, palm grip on small palms, and fingertip grip on large/medium and small palms. Personally, it is the first mouse that suits me for playing with fingertip grip.

Its optical sensor is custom-tuned by Razer with the name "Razer 5G Advanced" and reaches up to 18,000 DPI. As far as I have used it, it lacks nothing compared to the more expensive Viper Ultimate, and you can adjust the lift-off distance to 1 or 2mm through Razer Synapse.

Through Razer Synapse, you can also change the mouse's functions and add macros as desired.

The mouse's switches are the Kailh GM 4, modified by Razer with a lifespan of 60 million clicks. The Kailh GM 4 and GM8 are considered the best choices for switches on the market. It is quite nice that Razer chose to go with such a good option, unlike other companies like Logitech, which uses the cheaper Omron 20M switches in their €180 G PRO X, which are commonly used in budget mice.

It does not have any RGB, but who cares? As if the RGB is visible on the mouse.

I paired the mouse with Razer's Universal Grip (you can see my review there on Skroutz), and now I love it.
I also bought an extra lithium AAA battery and with the "AAA to AA" battery adapter, I now have the "ultimate weapon" in my hands. The mouse has slots for both AAA and AA batteries, but with the battery in the AA slot, I feel like I have better balance in terms of weight. Needless expenses that I made in order to like the Mouse even more.
