Copy of the Finalmouse Ultra Light mice. Of course, here we have a better implementation than the Finalmouse (for example, the Finalmouse reaches up to 500 Polling Rate while the Glorious reaches 1000). However, both have serious issues that don't occur in everyone but in many.
In terms of performance, it is an excellent mouse, as well as in terms of ergonomics and weight.
Coming from the Razer Deathadder Elite and Mamba Wireless, I saw a Deathadder that was somewhat smaller but almost equally pleasing based on my preferences. Of course, I was constantly bothered by the fact that it was smaller... but it's okay, it's just a mouse. It will do.
Unfortunately, it does have issues with its cable, which breaks internally and causes you to lose connection, as well as with its build quality.
For many, the left click has broken because it is too loose and moves left and right. I know people who have changed 2+ mice so far. But it is also a major problem for some streamers as well as on Reddit.
Also, Glorious has been facing crazy issues with its support, but I think they are fixing it over time by firing people :P Many of their staff members were aggressive towards consumers without finding a solution.
Of course, to mention the good things, they recently changed the cable by releasing a new version of the mouse. If what they bring to Greece or generally to stores in Europe are the new versions, and not old stock that warehouses are selling, then the issue with disconnections may not exist. However, this is a recent fix, so we still don't know their durability over time.
Especially for the price of 50+ euros that you can find it in Greece now, it is worth it if you don't mind dealing with difficulties and taking risks. NEVER BUY FROM AMERICA.
(Personally, I had paid 80 euros to bring it from Germany back then).
I hate mice with holes because it is very easy to create problems for them, and many Model O and Finalmouse mice on Reddit or from streamers that I have seen ended up having issues because of the holes.
The cable issue starts from the packaging, which squeezes it incredibly, and then because they made it unnecessarily very light, causing problems like that. Glorious has screwed many people, but they also sent a cable for them to change it themselves. They also changed their packaging to avoid easily damaging the cable. I believe that to reduce the risk of cable damage, it is good to use a bungee from Day 1. I recommend the Razer Bungee V2. I had the first one and I can say that I am incredibly satisfied with how flexible and stable it is.
Overall, we are talking about a very good mouse but with big risks and past issues. Quite sensitive but of good quality for an ultra-light mouse.
If you want an ultra-light mouse, I recommend going a bit higher in budget and getting the Razer Viper. Unfortunately, in case of issues with Glorious, you will either have a long wait from the supplier (probably importing from Germany), which in turn will have a wait from Glorious in America, or even a wait if you directly contact Glorious in case of issues.
If you are willing to wait and lose time, it is worth it. High risk, high reward. On the other hand, the Viper is from Razer, which has Greek representation and service, resulting in everything being immediate even outside of warranty.
Oh! If you are not specifically looking for an ultra-light mouse, my favorite Razer Deathadder Elite is currently at a great price. Ergonomic, incredible clicks and sensor, and well-made. (Trustworthy purchase if one considers that it is the Best Selling Mouse in the world with 10M sales)
P.S.: Currently, I have the G Pro Wireless and Viper Ultimate connected for everyday use and gaming.
EDIT: Razer Deathadder V2 was released at 80 grams with everything I wanted... I put everything aside. Back to the old one.
P.S.2: IF YOU HAVE GLORIOUS OR PLAN TO GET ONE, ALWAYS DO A FIRMWARE UPDATE. Glorious is a small company and while they do quality work (to a certain extent) in the construction of their peripherals, everything else is ALPHA TEST, not even BETA :P So we always look for whether a Firmware Update has been released in case we had any issues.
P.S.3: Giwrgakys13xXxSlayerxXx, I don't care if your favorite streamer has 5 Glorious mice because he wants to always have a backup because it's his favorite mouse for Fortnite. As good as this mouse is, it's equally bad. You get what you pay for. Also, he has 5 because Glorious sent them to him :v
Edit: It has now become known that it is a cheap and at the same time overpriced OEM with many problems in Support. You can find the same mouse at a lower price if you are interested, just from a different brand.
