Perfect mouse. Period.
Color: Black and Gold, Color: Black and Gold
LOVVVVEEEEE this mouse!!!! 20/10. I bought this for my new laptop and it was such a great value. I fell in love with how smooth and sleek it is, and how incredibly QUIET it is! This is the main reason I bought it, for the silence and the fact that it doesn’t click click click. So I immediately bought one for work since the one I have at work is so loud and clackety. Game changer. These are amazing. Love how they look, love how they feel in my hand using them, love how they work when using a computer, love how they fall asleep and save battery when not in use, love how they don’t make clicking noises or scrolling noises. Sooooooo good!!! Oh and love the price.

Very durable and pretty 😍
Color: Mint Green to Purple
The purple-mint gradient color is so pretty. It works well and feels nice in my hand. The buttons don't make a lot of noise, which is a bonus. Good for the price and haven't had any issues yet. You only need one battery and it lasts a long time. Installation is easy, just plug in the USB receiver, switch the button underneath to ON and you're good to go. No Bluetooth needed.

great mouse
Color: Black and Gold
really good mouse, the sound isn’t loud, i love the little scroller and ive used it daily for a few months now and the batteries life has lasted since then and i haven’t had to change them out which is great. it’s very lightweight and it will go into i think maybe a resting mode after not using it for a few minutes and you have to click to turn it back on which i do like. it fits very nicely in my hand and it’s overall a great mouse.

Quite clicks and easy manueverability. Works great.
Color: White and Gold
I was very pleased when I opened the box and seen that the actual mouse looks exactly like the pictures. It is lightweight and glides easily along my mouse pad. The colors are gorgeous and makes it look very chic! And it works great. It was easy to set up, just plugged in the USB receiver and it was up and running right away. The clicks make a muffled sound that is kind of soothing.

I hold this more than my husband's hand!
Color: Black and Gold
So much about this mouse is RIGHT!! The smooth feel in my hand, the way it glides across the mouse pad, and the silent scrolling and clicking feature are all great features I look for in a mouse. As an online college student, homeschooling mother, writer, digital designer, and business owner, a computer mouse is one of my most used "tools".
The battery life seems to be alright, although I did not realize it was ran on batteries and am not looking forward to the ongoing replenishment of that. I would prefer a mouse that charges if it were to be wireless or just have that cord attached. It responds with my computer and laptop well with little to no lag.
Visually, it is gorgeous, classy and professional while also being cute! The black with the rose gold colors really make a statement.
Aside from the longevity and sustainability of batteries, I love everything about this mouse. Show me this mouse with a few upgrades and the ability to charge an internal battery and I will be all over that with 5 stars!
