Easy setup, beautiful red!
Color: Red, Color: Red
I needed a mouse for an assignment when I asked my son for his. I loved it so much that I needed to buy myself one. I bought the red to match my computer (and to know that the navy blue is my son's) and it's a very sleek, not tooo vibrant color. It does come with both an USB & USBC controller (see pictures) and mine connected FAST to my computer. It does NOT come with a battery (most mice won't) so please grab a DOUBLE AA battery before it comes in so you will be ready. I have no issues with the mouse and loved the price point on this one. It's light weight and easy to setup. Then again it was a plug in/play setup, so if you're not tech savvy, you won't have issues with this one. Just choose a color and get it!

Cut the Cord and Never Looked Back!
Color: Grey
I'd been using a wired mouse forever and kept telling myself the cord wasn't that annoying. Spoiler: it was. The moment I switched to the WisFox 2.4G Wireless Mouse, I realized what I'd been putting up with all along — and there's no going back now.
Setup was dead simple. Plug the little USB receiver into the laptop, and it just works. No drivers to hunt down, no pairing headaches, no nonsense. The 2.4G connection is solid and responsive — I haven't noticed any lag or signal dropout, even when the receiver is tucked into a port on the back of the laptop. The cursor tracks smoothly across my desk surface without any skipping or stuttering.
The ergonomic shape is a genuine plus. It fits naturally in the hand during long sessions and doesn't leave my wrist feeling fatigued the way some flatter mice do. The buttons have a satisfying, tactile click without being loud enough to bother anyone nearby.
My one gripe — and it's pretty minor — is that it runs on batteries, which means you'll eventually need to swap them out. It's not a dealbreaker by any stretch, and the battery life has been reasonable so far, but if you're used to a wired mouse that just runs forever, it's a small adjustment to keep a spare AA or two around.
Pros:
Instant plug-and-play setup with the USB receiver
Reliable, lag-free 2.4G connection
Comfortable ergonomic shape for extended use
Great freedom of movement without cord clutter
Cons:
Runs on batteries — plan to keep a spare on hand
If you're still tethered to a wired mouse and on the fence about making the jump, this is a solid, no-fuss way to do it. Hope this helps!

OK, Mouse
Color: Grey
It is comfortable to use and it works as advertised.
The button click is soft and quiet, so there is very little tactile feedback. I often drop a selected object in a click and drag motion. The mouse is OK for general use, but I would not recommend it for CAD or art.
This mouse goes to sleep very quickly. I imagine this saves the battery. It doesn't wake on motion, it wakes on button click. With a laptop, the mouse goes to sleep after any short break. It behaves differently than other wireless mice.

Comfortable fit for arthritis hands and on the fly functions.
Color: Grey
I bought my wife this mouse in 2022 and she has had no issues with it. I had a different wireless mouse that I used that started causing issues in my everyday working and the speed and clicks of the mouse were causing issues. I decided to steal her mouse for a while and found, wow, this is great. I bought myself on and totally love the response I get. The DPI change on the fly is the game changer for me. You can instantly click to change the speed of the curser and make your clicks more accurate. This will be my mouse for choice. I have arthritis in my knuckles but, this mouse does not bother my hand at all. totally comfortable for a 12 hour workday.
