MK Frozen Llama Mouse 67g Lightweight Gaming 3389 Pixart RGB GM 8.0

It has worked perfectly, and feels great, and tracks great. Huge upgrade from my G502 HERO.

Rattle in the mouse from day 1, left click started sticking on or turning off while dragging about a month into use. Looks great though. Nice and lightweight.

Awesome lightweight mouse. I have bought several of them, first one as a gift for my wife but I liked it so much I bought a couple more for other systems. I especially like the no software part with all adjustments done with local switches on the mouse itself. The size, shape and functions are great IMO. Looks very much like and EC 1 or 2 clone. I very nearly went with a Pulser Xlight (very similar shape, looks like glides are the same as well) as it's all black but the local switches on this mouse is ultimately what sold me on it. Knocked 1 star off because the 2nd one I bought did develop a rattle inside and they do 'creak' if you squeeze the sides. That and an all black version would have been really nice. I am actually planning mod attempt to achieve an all black or blackout aesthetic, so I'll be opening up anyway but it is what it is. I have used it daily for about 3 months as of this writing and have been very satisfied with it's performance so far but it's lack of color options and the other miner gripes gets 4/5 stars. Overall the mouse is awesome, I recommend it.

Honest review after a year: Pros: - I like the look and feel of the mouse. I am not sure what a frozen llama is but that didn't detract from the awesome colorscheme. - The cord, switches, and scroll wheel are all high quality and have (for the most part) held up great over a year of daily use - The side buttons are the best feeling and most ergonomically placed of any mouse I have ever tried. Cons: - There is a rattle inside the mouse that you can hear under normal operation. I'm not sure how they let this go past the assembly line and after a year it is enough to make me slightly dislike the mouse. - The scroll wheel has lost its clickiness. I use the scroll wheel button to ping locations in games and it has began to occasionally feel a bit awkward to push, sometimes seeming to get sideways on me and not respond normally. - There is only one rgb mode which is rainbow strobe mode and I honestly hate it. Can't color coordinate with the rest of my build. At the time, I was very excited to support MK and their first foray into mouses. I think this could have been great if they just took care of that rattle noise on the assembly line!

It is not terrible, but I would not recommend it for any reason other than wanting it to match other Frozen Llama products. I also hear the rattling people have mentioned in reviews, but it I didn't even notice until a YouTuber pointed it out. Nothing I do while using a mouse would make rattling noticeable. It is a good light weight mouse because it has all the same hardware as all the other great light weight mice in 2021 - its pretty much an exact copy of the XTRFY M4. They have the same sensor, shape, USB cable, and no software requirements. The only cosmetic differences are that the XTRFY has all around RGB, an RGB mouse wheel, and a mouse wheel button. There is one HUGE issue that gives me discomfort with the Frozen Llama mouse: it makes my hand very sweaty. I dont have this issue with any other mice I own (Corsair Dark Core, Corsair M65, Logitech 305, Logitech 508, Model O-, and the XTRFY M4). So I think the XTRFY M4 is a better purchase between the two as it only costs $59.00 and the shell material doesn't make my hands sweat. Out of all the lightweight mice ive used XTRFY M4 is my favorite thus far.
