ProtoArc EM11 NL Ergonomic Mouse, Wireless Vertical Mini Mouse Rechargeable Optical Mice with Multi-Device (2*Bluetooth + USB Connection), 3 Adjustable DPI for Computer, iPad, Mac, Windows Black

Very pleased with this mouse. I bought it because I have recently been suffering with tennis elbow and it was suggested that using one of these might reduce the pressure on the tendon which causes the pain and the joint itself. It took a bit of getting used to, coming from a normal mouse, but I soon got used to it and find it extremely comfortable to use- your hand/arm is in a more natural and relaxed position, putting less stress on the elbow, as it is no longer twisting so much. In terms of setting up, the tiny usb bluetooth dongle set itself up in Windows 11 straight away and connected to the mouse with no problem and I've had no issues with disconnects or connections from the bluetooth connection. The mouse feels solid and well made and is of a soft feel/matt texture, so very comfortable to use and feels as though it will be durable over time. It seems accurate, I've had no lag or skipping of the cursor during any normal use. I've not tried gaming with it yet. For me, it's been worth the money - I'd seen these before and wondered if they were a gimmick, but since I've been using it (combined with an erganomic keyboard from Arteck), I can now see that it isn't and it has reduced the pressure on my elbow/tendon which has in turn reduced the pain. It might not be for everyone, but it's a thumbs up from me.

Having used this product for about 8-12 months, I can honestly say this is an amazing mouse. It does relieve strain definitely. It tracks very well and is easy to use. Feels natural coming from a standard mouse. One thing that is an absolute stand-out feature is the battery life. I’ve gone months without charging it using the 2.4Ghz module, and only charge it when I randomly remember. After almost a year, there is no major wear on the mouse anywhere, using it daily for 8 hours a day. Buttons feel clicky, and everything is smooth. Only thing that might wear out first is the feet. But maybe after 3 years. Great product, great price, great functionality, no lag on windows.

This is generally a great mouse, has really supported me to continue to use a computer and is easy to use, smooth tracking and is a great fit for my hand (medium female hand size!). I've had no issues with Bluetooth or wired mode and great value for money. It seems well made and does what I need it to. The only slight issue is it takes time for your fingers to remember where the left and right buttons are and I still often find it difficult to use without looking at the buttons but this will improve with time.

Nice quality materials, good design & feels very comfortable to hold. Easy to set up. So far, so good! Hopefully it will cure my wrist ache.

I love this mouse. I needed a mouse that was more vertical as I have been suffering with my wrist and was recommended this type of mouse for my office job. It has great functionality incorporating the use of two Bluetooth devices and a usb dongle. It is very responsive and is charged up by usb-c. The feel and quality of the mouse is really good and a really nice shape to hold and reduces the need for twisting the wrist. I love the colour, I got blue. Great price and does exactly what it should do. I would recommend to anyone.

I am rarely moved to review an item, but this mouse is such an improvement on my previous (Microsoft) wireless mouse that I just had to write one. The first nice surprise was that the mouse is rechargeable via a little USB-C port underneath the grip. Having been used to supplying endless batteries for my previous mouse I was really pleased about this. It was really easy to connect the mouse to Windows (using my previous mouse!) via the Bluetooth options in Windows 11, and once connected, it stays connected reliably. This is another bonus as I don't have to use a USB port for the optional included USB receiver, which is slotted into the base of the mouse. I can keep this option handy in case I need to use the mouse elsewhere or on a device without Bluetooth. The mouse itself is incredibly easy to use and comfortable to hold. The curve is perfectly matched to the open grip of my hand, and the buttons are perfectly placed for clicks. The surface material is very smooth yet slightly rubberised so you don't lose contact while using it. Talking of clicks, the mouse buttons are responsive and the clicks are precise yet also soft, so there is less noise than my previous mouse. The mouse is very smooth to move across my desk, and due to this it feels almost weightless, like an extension to my arm. The scroll wheel is responsive, with subtle 'stops' as you turn it, but provides smooth movement through documents or for zooming. The DPI setting, which I haven't adjsted yet as I haven't felt the need, makes the pointer move fluently on the screen, and for this reason I feel I am working more efficiently and smoothly than I was before with my old mouse. Overall I would say this item is exceptional value for money, really well-designed, and I would recommend it highly for anyone needing a new mouse for either productivity or gaming.

This arrived very promptly and beautifully packaged, it’s rechargeable so batteries not needed-great. Great value for money and very good quality, I have used a vertical mouse before made by Anker which was ideal for my small hands but decided to try this one as it looked easy to use. Unfortunately this is not suitable for small hands, if I had large hands I’m sure it would have worked perfectly. The reason for buying vertical is due to arthritic fingers and using a standard mouse has become painful. My short fingers only reach about halfway and I found it difficult to use the scroll wheel and when clicking on the button I kept clicking on the orange back button too. This would definitely suit medium to large hands but not short pudgy ones like mine. Have attached my own photo (forgive the old wrinkly hands) together with one take from another review to give you an idea of what I mean. Unfortunately had to return this, I would have given this 4 to 5 stars but as it was unsuitable for me have had to give it 3.

I wanted a new mouse as my latest laptop had no USB-A ports. I tried several mice and despite my initial preferences, this was the mouse that I ended up buying; my hand just naturally went to this one. It's just comfortable and the buttons are all in the right place - at least if you are right handed! It is a large, basic mouse, with the usual left click, right click and clickable scroll wheel plus two other buttons for forwards and backwards. There is also a button next to the scroll wheel that allows you to adjust the mouse's sensitivity should you want to (1000/1600/2400 DPI). It came beautifully packaged in a smart box, with charging cable (USB-A to USB-C), Quick Start guide and manual. The EM11 NL weighs 132g (3.9oz), measures 138 x 69.2 x 68.1 mm, and is covered by a two year guarantee. Unlike my friend's Logitech mouse, the buttons aren't programmable and the scroll wheel cannot be set to freewheel, but his cost £70+, while this one cost £19.99 (reduced from £24.99) You can connect this mouse to up to three devices; one via a USB-A dongle and the other two via Bluetooth. Switching is very easy using a pushbutton on the bottom of the mouse. Power is from integral, rechargeable 500mAh battery with a USB-C charging port and a USB-A to USB-C charging cable supplied. Charging takes 2-3 hours, but lasts a long time. A red LED by the scroll wheel indicates if it needs recharging. There is an on/off switch on the bottom that conserves power when the mouse is not in use.
