I have been using this mouse for over a year now, and its performance has been brilliant. I am using it with my Macbook Pro and it was such a relief to find that I could customise the shortcuts for workspace/desktop switching, launchpad, and mission control on its different buttons with the "Logitech Options.app". Moreover the bluetooth pairing is swift and there's almost zero lag. The light indicator subtly shows a tiny blue notification for pairing, or lost connection & automatic repairing (which happens momentarily, roughly once or twice a week with heavy usage), and turns red when battery is low. Even with the battery low indicator on, the mouse worked perfectly for about a week until I replaced the AA battery. The mouse isn't heavy, is responsive, and there's no hassle of a bluetooth dongle. I use the mouse extensively with Photoshop, Illustrator, Sketch, AfterEffects and Browsers, and the precision and control is just impeccable. A real worth for money, bought for 1.8k in Sep, 2016.

Initially I was a bit uncertain about the price as I have always used cheaper mice, and ones that have a dongle cost almost half as much in some cases. But upon using it my perception changed. Syncing is super easy on my laptop and phones, it's very responsive. More importantly, it is very comfortable. The small button also serves well as a task manager / app switched, which is a pleasant surprise. Even the scroll does something new with swipe actions!

I am really liking the mouse after first day of my use. It's highly responsive and functioning as expected. Really happy with Amazon delivery.Only thing, I ordered a black mouse, but I got grey and yellow. I mean why would I want that. I guess it's just one of the cons of online shopping. I would have really liked a black one as it is one of the items that I would use daily and long term.
