I have Med-Large hands which I think is important to remember when you read this review. Hand size is very important when you're considering vertical mice. For me, I switched to vertical mice due to carpal tunnel a couple years ago, and it really helped to eliminate it. I went to Best Buy and tried both the Logitech Lift and MX Vertical. The Lift is for smaller hands and I didn't like the feel of it. So I bought the larger MX Vertical despite the $100 pricetag with the hope that it'd help my carpal tunnel. It did, but unfortunately, now its suffering from the double click issue that apparently is a feature of Logitech mice. So I began the hunt for another vertical mouse that didn't cost +$100. I knew I wanted one that was for Medium to Large hands, so I tried 3 different ones that said they were for larger hands or had similar measurements to the MX Vertical. None of them I ended up keeping for various reasons. So I bought another one hoping for better luck.Pros: This mouse feels great in the hand with a nicely textured surface. It also has some of the most satisfying buttons of any mouse I've tried with a very tactile yet soft, quiet click. The scroll wheel is nice much like the MX Vertical. The shape was exactly as described and felt like a hand shake. Despite the smaller size, I really enjoyed holding this mouse and my wrist did not drag on the mouse pad. Finally it has a rechargeable battery (which can be a con for some) and was under $20. It also comes in different colors.Cons: The con is that my hands are too big. They recommend this mouse for S-M hands vs the M-L of the others I tried, and I definitely agree. My little finger drags horribly if i put my hand in the "correct" placement. I got around this by putting my 1st finger on the left side of the first button and my 2nd finger on the right, and then use my 3rd finger as the right click, which gave my pinky room on the mouse. It worked okay but wasn't ideal. I really wish ProtoArc made a super sized version of this mouse. (Side note: I saw a knock off version of this mouse with the exact same measurements that said it was for M-L hands. Thank you ProtoArc for an accurate description)Ultimately I ended up returning it due to my hand size, but I really wish either my hands were smaller or the mouse was larger so that I could have kept it. Please ProtoArc, make a larger version for those of us with larger hands. If you did that, I'd buy it immediately.

I've heavily used computers for both work and gaming for decades. I don't generally get pain or soreness in my wrists, even with heavy use, but as my good friend 'time' has shown me, all good things must come to an end.These days, after extended use, I've noticed hands and wrist are getting tired, sore, and every now and then actual wrist pain, so I've finally taken steps to make my setup more comfortable and ergonomic.One of the things I've seen a good deal about lately were vertical mice - had never used one, but was curious to check one out. It make sense, right? That a better angle would be better for your wrist, so I went ahead and purchased this one.After using it for a few days, I am an absolute believer. It did take a day or so to get used to, but now that i'm used to the positioning, it feels so good. Wrist definitely feels more comfortable.With the actual mouse itself, it's pretty cheap, but works well.-Click response is nice. Nice feel to it-Have experienced zero connection problems, so far works great-Nice position for the charging port, no issues using it easily while plugged in-Weight is lightHonestly, aside from adding a few more buttons that you can program, and maybe higher DPI options, this is a great all around mouse that while it does take a little getting used to, once you do, it's a game changer.

Fantastic mouse/keyboard combo. The mouse took some getting used to, because of my larger size hand, but I adjusted by using my middle finger on the left click giving me a more natural feel. I hope they come out with a 2nd version for larger hands. The battery life and comfort are amazing. The mouse has really responsive DPI control, and the button layout is user friendly. All-in-all a very well designed, low profile ergonomic device.

As someone who spends long hours both thinking strategically (chess 🎯) and working intensively (college, resumes, online work 💻), I’ve put this mouse to the test in real-world, daily multitasking. Here’s what stood out:⸻✅ Pros• 🖐 True Ergonomic ReliefThe vertical grip instantly took pressure off my wrist both in fact. As Someone with a cyst in my wrist this was a huge relief!!!! Very crucial mouse for someone who types for hours and occasionally has to pause between chess games or college papers due to hand fatigue. It feels more natural, like a handshake rather than a claw.• 🔄 Seamless Multi-Device PairingI use multiple devices (laptop, Chromebook, and sometimes a tablet), and switching between them is effortless with the multi device connectivity. No annoying unpairing/re-pairing. This is a multitasker’s dream.• ⚙️ Quiet Clicks, Precise TrackingIt’s stealthy—perfect for libraries or quiet environments. Cursor control is responsive enough for both fine document editing and rapid screen shifts during Zoom calls or multi-tab research.• 🌐 Cross-Platform CompatibilityWorks well on both Windows and Mac. I’ve tested this on different systems in college labs, and it holds up with no lag or driver issues.❌ Cons• 📏 Slight Learning CurveIf you’ve never used a vertical mouse before, your hand will feel confused for a day or two. But once it “clicks,” you won’t want to go back.Overall a very great mouse that is built to last and is very comfortable once you get used to the design!
