Extremely lightweight! Good grip though, nice click feel both left and right and on the scroll wheel. The small "Forward" and "Back" buttons are in the ideal position. Good software, it offers capable customizations but all customizations only work when the mouse is connected via infrared while they disappear when connected via Bluetooth. At least on MacOs...

5 Stars for what it is. Personally, I would give it 4, but in this case, "It's my fault" (not yours, I'm the problem. The frequent excuse). I am an Ergo Mouse user, but I can also use Claw Grip normally; I just don't prefer it.

But why 5! Its only "Flaw" is that it is not Ultra Light; it is light, but such a Mouse is usually 10-15 grams lighter. However, very light is not for everyone, but light is good for wrist health. Depending on the size of the Mouse, under 80 grams at least.

The reason it is not that light is that while it has holes and is made from material used for "Ultra Premium Lightweight Mouse," Keychron chose to make the walls of the Mouse very thick compared to its competition to ensure sturdiness. After a month and a half of daily use, there is zero cracking or flex. No matter how much you press it, nothing moves. Rare in general for a light Mouse, rare in general basically for today's Mice that cut weight from their bases. We have even seen Mice like those from PWNAGE break because they are too thin, even if they are made of Magnesium Alloy.

It is the closest "clone" to the Razer Viper Mini Signature Edition (worth €300) and generally to the Viper Mini, one of the most well-known if not the most well-known Fingertip/Clawgrip Mouse on the market.

Its Wireless was flawless; I am a bit biased, of course, because I still believe that Razer and Logitech have the best Wireless on the market, but I certainly did not have any issues like disconnects. I don't have the equipment to test its latency or anything to compare it with others, but in use, it didn't seem to "lose" in anything.

Very little pre-travel on the buttons; I don't know if it's my unit's fault, but I mention it. Not annoying, not something you notice unless you try to see if it actually has it.

It supports 4K Hz Polling Rate, connects via 2.4Ghz USB, Bluetooth, or with a cable. Its Wireless Dongle is the most beautiful Dongle I have seen, a mini 75% Keyboard, very beautiful and smart design compared to the "common" ones on the market.

Overall, for anyone looking for a small Mouse, I definitely recommend it. If you are looking for Magnesium Alloy construction, even better because it is VERY cheap in this category.

I always wanted the Razer Viper Signature Edition but it costs €320, only from their site and only if you manage to find it (it's always out of stock).

Well, this here is essentially what I was looking for. It fits perfectly in my hand, I hold it perfectly, it doesn't have mysterious rubber parts that will wear out, it's lightweight, sturdy, metallic.

The only downside I can think of is that it doesn't have a charging dock.
