Extra button?

[This review was collected as part of a promotion.] This is very light weight! It’s pretty. Easy to connect to your Bluetooth device. The grip isn’t like the other Logitech units. Some may love it but I didn’t. There’s a button on top that I need an explanation on what it does…?

[This review was collected as part of a promotion.] Very comfortable to use! It's very smooth and very fast. I especially like the fact I can use it on multiple devices and that I can set up shortcuts with custom buttons.

Logi mouse

[This review was collected as part of a promotion.] I received this product from Influenster in return for an honest review. I’ve been using it for work for a few days now. At first it took some getting used to lol. The button and scroll are super sensitive and it’s a different shape than I’m used to. However, I quickly noticed it’s more comfortable for my hands and wrist! I really like it and it has now replaced my old mouse. Highly recommend! Easy to setup and connect to Bluetooth too.

Comfortable and easy to connect

[This review was collected as part of a promotion.] I absolutely love the Logitech Signature Comfort mouse with Bluetooth connectivity. This mouse is literally the most simple thing to connect to your computer. Unbox, and turn on Bluetooth on your device - that's it! It couldn't be any easier. I love that I don't need to take up another USB port on my computer, and how smooth this scrolls. There is also no noise when clicking which I appreciate. The side buttons are customizable and I'm SO HAPPY to see Logitech using recycled materials to make this mouse. Not only is it comfortable for your hand but it's better for the planet. I'm very pleased!
