Update:
Stay away!!
A few days before completing a year since the purchase, it broke.
No matter what troubleshooting I tried, it didn't work, just like for those who had the same issue based on what I found in my search...
It simply doesn't want to function:
Constant drift to the left, slow, with intermittent cursor scrolling on the screen as if the PC is overloaded or as if someone is remotely managing it and there's lag.
Only when it comes to the mouse, everything else on the PC and all applications work fine.
It simply doesn't respond no matter where you move the cursor.
Also, it doesn't enter pairing mode if you switch it to Bluetooth.
It's simply useless now...
Such a shame, it served me well...
Stay away!!
Less than 1 year for Razer, 3 for Trust, and it came out of the box again to save the situation!!

(Initial impressions below, in a formal manner)
Don't want to read long texts?
If you don't need 500 different keys for professional gaming or work,
YES, it's worth buying.
The reasons are explained below in my comment.
It's relatively large but very convenient.
I've used several wired mice in my life
(with the Intelipoint from Microsoft being the third and the mouse from Amiga 500 being the first!),
as well as two wireless ones, one being Bluesky which was decent but suffered from signal loss when it was 10 centimeters away from its receiver (basically, I suffered XD), clicks that didn't register regardless of the distance, etc.
and another one being the "Microsoft wireless optical mouse 2.0" (with 3 buttons and a scroll wheel) with similar issues,
resulting in me switching to CM Devastator (which broke in a few months)
and a Trust Ziva which surprisingly lasted close to 3 years without breaking, with its only downside being that it's wired.
So, the last one ended up in the closet as a backup, because as soon as I connected the Deathadder and installed the accompanying software (it automatically starts the installation process with step-by-step options on Win10), I realized that I was "locked" with it. From the button placement, weight, and ergonomics, I was simply "locked"!
It was installed with the 2.4G stick on the desktop and connected via Bluetooth to the Cosmote Android box.
So, I can work on two machines with just one mouse. Anyone can do the same, as long as one connection is BT and the other is 2.4G, regardless of the device.
For example, 2 laptops or 1 desktop and 1 laptop or box or tablet or...
Simply put, after the initial connection to each of the two machines,
I just switch the button underneath and control the machine I want!!
I adjusted it through the "mother" application to go into sleep mode after 15 minutes of inactivity, and that's it.
The dual battery slot is a plus for me since it doesn't have a permanent/integrated battery (you only insert one battery to make it work), which means:
a) You can use whichever battery you have from the two types (AA or AAA) and get your work done!
b) When the battery dies, you throw it away and insert a new one, just like you would with any other battery - and you don't throw away the entire mouse!
c) By changing the battery type, you also have a difference in weight if you want it lighter or heavier.
d) You can simply use rechargeable batteries (which is what I do), so the issue of sleep time and battery consumption doesn't bother me at all!!
The "grainy" surface bothers me a bit because it gives the impression that it will accumulate dirt relatively quickly.
As for durability, we'll see in the future. It arrived today, so I'll update if there's anything new or an issue.
