I've gone through some of the reviews, and could find many are facing connection problem..

There's nothing wrong with this device, basically all the bluetooth devices have this problem.. By default OS powers off this device to save power of your system..

To sort out the problem you'll have to disable the feature, go to "DeviceManager > Bluetooth > Bluetooth USB Module > Properties > Power Management >" and untick "allow computer to power off this device to save power" feature..

Nice mouse.. Compact but fits in perfectly for long duration. Doesn't leave cramps on the fingers or above. Clicks give a nice feedback. Scroll wheel is smooth.

With the set point tool u'll get lot of customizable gestures. The best part is its bluetooth, so saves a USB port.

Overall a good buy. Highly recommended.

I wanted to connect my win 8 tablet to my TV. Once that was done I wanted a mouse that could work from far (TV viewing distance) . This thing connects fast and works like a charm. But there is a little lag sometimes or gets stuck sometimes (just 1's or 2's). the biggest advantage is its battery life, configuration of its buttons the way you want it and long distance

Everything is good except sometimes when system wakes up, reconnect is not happening.
Need to manually connect sometimes.
I recommend this product, its very good with small negligible problems.

My Review update after six months of use:

Working very good, best of this is it has no dongle too, so just wireless Bluetooth connection.
I am using this for my Sony Vaio and works fantastic except the issue mentioned above.

I am using this with MacBook Pro and it works well.
Pros:-
- Cool design and buttons have a nice feel when clicked and appear to be durable.
- The sensor doesn't emit any light.
- Detects mouse movement perfectly.
- Ergonomic and comfortable to use for long duration's.
- Battery life seems to be good, I haven't switched it off once in the last 2 months but it's still up. I use it for couple of hours every day.
- The Middle Button tilt feature and the extra windows button are easily customiza...

Have been using the mouse for a month now. Build is good(however, i would'nt risk dropping it). Works flawlessly with Windows 10 and OSX.
Needs additional software to configure buttons on OSX but is easy to setup.
Only con i can think of is that its not innovative enough for the current market, i mean it works well as a 3 button mouse but no configurable side buttons or trackpad(like the apple magic mouse) etc.

This is an excellent product. I have been using it.

Had to follow a few steps like a user pointed out :
Go to "DeviceManager > Bluetooth > Bluetooth USB Module > Properties > Power Management >" and untick "allow computer to power off this device to save power" feature.

This happens as the operating system powers off the bluetooth module when inactive to save power.

The mouse is good looking and is light weight too. Built quality is pretty neat too.
Those of you who have 2 usb ports and ...

No problem pairing and connecting each time I switch on the laptop. Slightly smaller but not too small like an usual laptop mouse. Windows key is not very usable because of its position, but the side kick functionality of the mouse wheel to the left and right is useful when browsing.

Would have given 5, but the bottom panel is a bit narrow towards the front side of the mouse and is prone to breakage if the mouse falls down.

Overall I am happy with the mouse. I am using it with Lenovo T440...

Bought for using with my tablet via blue tooth. Easy to set up. Uses standard batteries. Using it for two weeks now, batteries still going. Cash on delivery, easy to order, good tracking information.

It is a featured packed mouse which I was searching for. The design is pretty cool and it looks expensive too. The build quality is good and ergonomic ally designed. The seven button can be configured as per your choice. It is easy to install and uses 2 AA batteries. Bluetooth connectivity is quick and I connected it with my phone too which was working absolutely fine. 3 years warranty, 12 months battery life what else you want. Would definitely recommend this product to all who are in search...
