ProtoArc EM11 NL Wireless Ergonomic Vertical Mouse, Rechargeable, Blue | Multi-Device with 2*Bluetooth & USB, for Small to Medium Hands, 3 Adjustable DPI for Computer, iPad, Mac, Windows

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.

I bought the ProtoArc EM11 NL on a whim looking for a solid ergonomic option, and I am absolutely blown away by the value here. "Amazing" doesn't even cut it. My daily driver is a high-end Logitech MX mouse, so my standards for ergonomics, build quality, and comfort are pretty high. I fully expected this to feel like a "budget backup," but it feels incredible in the hand. The contouring is spot-on, the grip is comfortable for long working hours, and the tracking is incredibly smooth. If you are on the fence because of the price point, don't be. To get this level of premium feel and comfort at a fraction of the cost of a mainstream flagship mouse is a total steal. Highly recommended!

Good: -- Much higher quality than its price would suggest. -- Very light, even with a built-in battery. -- Seamless Bluetooth connection. Bad: -- The wheel cannot spin freely! If you are used to the Logitech way of giving the wheel a spin to get back to the top or bottom of a page, then this click-click-click only wheel will irritate you. -- For smaller hands. I actually get some wrist cramp from using this because my fingers are a bit squished together on the buttons and wheel.

Huge thanks to the Switch and Click YouTube channel for pointing this one out. The ProtoArc EM11 NL arrived in surprisingly premium packaging, and the build quality is outstanding. It is exceptionally comfortable to hold, offers plenty of configurable buttons, and features quiet, dampened clicks that make standard mice feel obsolete. I used it for just a day before ordering a second one for my partner because the design is simply that good. Finding this level of design and ergonomic relief at this price point is rare.

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.

Excellent mouse except for one weakness - the scroll wheel stops working properly after a while (as quite a lot of other reviewers have commented). Mine will scroll up, but only scrolls down intermittently. The fault developed after less than 12 months of use. If it wasn't for this critical issue I would give it 5 stars - it's comfortable to use, the buttons work well, the matt finish on the plastic provides a good non-slip grip and looks nice, and the shape and size are perfect for my particular hands. If only ProtoArc would fix the unreliable scroll wheel mechanism...

What can I say about this mouse? It feels like pure premium quality. The ergonomics are perfect for various hand sizes, and it's very easy to keep clean. It glides beautifully across surfaces, and the Bluetooth connectivity is surprisingly seamless. I mostly use the wireless dongle connection, so having both options included is a huge plus. The unboxing experience was great—it comes with the charger and even a note from the designer. If I could change one thing, I’d move the thumb buttons just a few millimeters higher. I might just be used to different ergonomic mice, so my muscle memory is looking for them elsewhere, but it’s likely just a matter of getting used to the new layout. Overall, I love it.

Purchased and love it. forget im using one as its so comfortable. one thing reading the negative reviews. i.e a guy showing a video claiming no grip. grip is perfect. the guy is a "Insert word here" using a mouse on a shiney wooden table. like dude get a mouse mat lol. all mice do that on shiney slidey surfaces. THEY HAVE SLIDERS ON THE BOTTOM. pairing? yes dont know why people claim it doesnt pair. it works first time. bluetooth and or use dongle sorted. both work perfect. id say they have more hardware issues than it being the mice fault honet opinio. mouse is great. use it for my design and work. bargain

Mouse works as advertised. Have noticed relief in my wrist since using it. Nice build quality and packaging gives you the 'premium' feel.

Bardzo polecam produkt - nie mam już dolegliwości i bolącego nadgarstka. Ponadto od dnia zakupu produkt nie wymagał ładowania więc co najmniej pół roku na baterii przy codziennym użytkowaniu.

Absolutely great, good sensor, great comfort, has good connection options, and rechargeable battery lasts months on end (I've only had to charge mine twice and I've had it for a year - but I turn it off when I'm not using it). Also, you can keep using it while it charges, which is awesome. It even works on my glass table!!! (-> Not super well, but very usable - though I tend to use a mousepad instead because its more comfortable)

Me ha sorprendido su calidad. Packaging muy cuidado. El tacto es muy agradable y el click silencioso. La ergonomía perfecta. Sobre las batería aún no puedo opinar porque me acaba de llegar. Después de probarlo por casi 2 meses puedo decir que estoy contentísimo. He probado varios ratones ergonómicos y sin duda el mejor. Comodidad absoluta, calidad, ergonomía... Han desaparecido mis problemas de epicondilitis. La batería increíble, aún no he tenido que cargarlo!! Usándolo durante dos meses, 8 horas al día y ahí sigue. En otros ratones la batería me duraba como mucho 1 semana. Conclusión, si me tuviera que comprar otro, repetiría sin duda!!

Es el primer ratón ergonómico que he comprado. Ya conocía este tipo de ratón. Pero tenía cierto escepticismo. Los primeros días son para acostumbrarse, pero luego su uso se vuelve natural. Después de unos días de uso me siento más cómodo. El ratón es bastante preciso y silencioso. No sé si es bueno para los juegos porque no juego. Pero para el trabajo del día a día me parece muy bueno. El ratón parece tener una buena calidad de construcción y una buena ergonomía. Tengo una mano promedio. Preste atención a las medidas de las manos. Me gustó mucho la presentación del producto en la caja. El soporte por correo electrónico (Europa) fue rápido y muy amable al responder mis preguntas. Además de cargarse conectado al PC, según el soporte, este ratón se puede cargar con un cargador de pared 5V -1A.
