Was disappointed it didn't work with my older bluetooth adapter so I had to order a new bluetooth adapter. After new adapter arrived it paired no problem, and I have begun using it for my desktop. It also worked no problem pairing to my nexus tablet right out of the box.

Works with Bluetooth 4; neat magnetic battery compartment

lower hump takes getting used to; It did not work with my old bluetooth adapter v 2 or 3

Great looking keyboard and Mouse, does not come with BT dongle, apparently it supose to work with laptop or other mobile devices with Bluetooth built in. Was purchased for our National Sales Manager that asked for it. has that same setup at home and he loves it.

Looks nice, but has a bug with all the media keys that causes the keyboard to freeze. Bug has existed since May with no fix from Microsoft in sight. https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/media-keys-doesnt-work-on-microsoft-design/15021270-fd88-4dac-b2b7-0b54afe2c12d

I bought this mouse to use with my laptop whilst out and about as I needed something portable. I bought this as it seemed to be one of the slimmest available and of a good brand. Pros: It's easy to connect for first use and is generally very quick to reconnect thereafter.

Beautiful but it has a problem, since it doesnt have the small usb receiver, the bluetooth connection is not reliable. I could accept the fact that it bugs for a really short amount of time (0.5sec) because it looks good, but now it doesnt work anymore. It even says that its connected.

Very glitchy and keeps disconnecting and big delay

The Microsoft Designer Bluetooth Mouse feels great in the hand, the button clicks are nice and solid, it feels like a more expensive mouse. Even the battery door has a good feel about it. The only issue I have is the wheel is a little tight, but I expect that to wear in nicely.

I bought the mouse within the past 6 months and have had several issues with this one. The mouse would randomly shut off and when turned back on, it would go into pairing mode, instead of connecting. Using it the other day and the track wheel somehow broke.

I bought this for its flat profile and therefore ease of storage in my briefcase. It's as I expected and slides into a small pocket that previously held business cards. Paired quickly and no problems so far (3 weeks in).

The mouse performs exactly as expected. The buttons and scroll wheel work perfectly. It is a two button mouse and low profile. I've seen other reviews talking bad about it and their reasoning is flawed. It is very low profile and can be seen as such while still in the packaging.
