Features

Comfort for wherever you work

Portable and elegant, the Bluetooth Mouse Slim lets you set up and get to work with all-day comfort. The sculpted design supports your hand for a good grip and it's slim enough to slip into your laptop bag so you can keep it on hand.

Pairs up with ease

Pairing the mouse is as easy as following the instructions in the pop-up on your laptop. When you put the mouse in pairing mode, your laptop will discover it, and you can quickly connect and get back on track with wireless comfort.

I really do not understand all the negative comments and poor reviews? It is EPIC!!!!???? Compact, sleek, easy to use and set up, works with all my hardware, beautifully built, well packaged, ordered yesterday and arrived today, set up in seconds. I never thought I would find myself getting this excited about a mouse - but its THAT GOOD!!!!! Well done Samsung!!!! My mates said it looked and felt better than the "competition" and also way more responsive as I used it on any surface including my leg and works flawlessly so yes, why all the hate?

This is a great mouse and perfect for all uses, the battery life is perfect, and the connectivity is great, however I fell for the price i paid I could have bought a better mouse from more dominant companies.

This mouse is overpaid. If it was £10, I would say it's a good price, but for £52... I purchased this mouse while buying a laptop, and I use a £5 mouse over it now.

I have had the mouse since the 1st August 2023 and it has stopped working less than 2 month later. Bluetooth stops connecting all together, it does nothing. Customer service has been terrible. I can only assume they do not care as it is not one of their more expensive items.

Bought the mouse at the same time as my Book2Pro 360 as wanted a wireless one but without the receiver given the laptop only has USB C ports. Activated it and soon as I did that it popped up on the laptop and was paired in less then 10 seconds. Automatically pairs every time you switch it on and is very quiet when clicking making it excellent for use in university

The first mouse I have bought in a long while, so I can't say how it matches up with the current competition like Logitech. It is a little pricy for a mouse, but I bought it to match my Silver Galaxy Book 2 Pro 360 and Multiport Adapter. I find it pleasant to use and responsive, and it also works with my Galaxy Note 10+ 5G. To people asking how to charge/change the batteries - it takes a single LR6/AA battery. To change this, place your thumbnail under the edge of the cover at the base of the mouse and lift. It's only held on by magnets. There are also a couple of locator lugs at the front that must be correctly aligned when replacing the cover.

Really good & useful mouse. Goes perfectly well with my Galaxy Book 2 Pro. Very fast & east setup. No USB required & pairs wirelessly via bluetooth. The clicking noise sound is very low to non-existent which is excellent. The downsize are that is very slim/more flat than curved which makes manoevering the mouse a bit tricky. Also a bit too squared. There is sometimes a bit of a lag when using the mouse however not too much. Finally, it works better on a mousepad rather on a desk. I would still recommend this if using a Samsung device however do feel the competition from other brands like logictech & dell are slightly bettwe.
