This product is definitely worth the price. The glass middle mouse button acts more like a trackpad with gestures such as vertical and horizontal scrolling, and "back" and "next" in Internet browsers. The curvy design takes a few days to get used to, but after using it once, you wouldn't want to go back to a mouse with a wheel again!

The only con is that the ON/OFF button is directly underneath the mouse buttons. So, sometimes you may click something unintentionally while going to switch off...

After using 4 other WL mouse, I ordered this one. Using it for last 2 months continuously without any problem. size and look is really appropriate for laptop as well as desktop users. Good built quality and very different design.

I've always been a fan of logitech products, owned quite a lot of them since my first pc back in 2003..
This one here is the best one i've used, far better than the M187, M185 and M235 mices.
Best thing is that you get 3yrs warranty than that of 1year for those M series mices..
and second best thing is its not small like those M series mices, it large and handy but a bit small than those desktop mouse.

Now about the mouse...
- it works flawlessly on Windows 7 pc. both horizontal and vertica...

great mouse ... Good range... middle mouse part is smooth too and you can customize it in many various using the logitech software.... I just miss the old middle scroll wheel which i am used to and it will take time to get used to it because everyone doesn't own a bitch like this... Love the product ....

1. No red light emission, this is a laser mouse.
2. super silent clicks, I work late in night.
3. double tap on the photo to zoom 100% and double tap to zoom out. (I love this feature)
4. middle touch area scroll is really smooth.
5. button quality and build quality is very very good.
6. middle button has 2 buttons, one lower and one higher, you can use the middle button to open start bar or change it to a window switcher button, so all the open windows will appear as small tiles and you...

I just bought it few days back.. its really feels good in your hands.. love this product.. if you go for any product i will recommend this.

update today is 20th November 2019 . it's still going strong it's unavailable now but if you get hold of this buy this. totally worth it

Its a very good product, Does not have wheel like traditional mice. Sensor does the job very well. Plug and play hasslefree... MUST HAVE for laptop users. very satisfactory !!!!

Am really happy to be part of the product. Its special mouse among the others which have seen or purchased.

Especially the scrolling middle button is very impressive. Buy and feel the difference in between the regular mouses. Shape of mouse is add-on, its power saver enabled which is very effective to save the battery less usage and the long run.

Just got the T400 mouse through the super fast Flipkart delivery. Started using it immediately and it works well. The size is slightly bigger than the mouse I use the Logitech M185 and will take a little bit of time to get used to after using the M185 for a few years. The center touch pad in place of the wheel is very sensitive and will need a bit of practice to get fully used to. Keep pressing down on it instead of sliding my finger. Otherwise a great unit and great looks too.

As usual , WS Retail + Flipkart deliver the products at the speed of Bugatti Veyron. I ordered it on 24th of April and it came on 26th. It can't come in one day because the One-Day scheme is yet to come in our city. I bought it for my father on his b'day. Now to the mouse , starting from the rubber grip around the lower side of the mouse :- it's really grippy and doesn't come in between while using the mouse. It's medium in size and the hand doesn't pain while using. The upper side is made of...
