This is the rolls royce of touchpads. Wireless, responsive, accurate. Shame they are so rare now.

I was running into some problems with my right hand and using a mouse. i couldn't manage to use the mouse with my left so i went looking for a touch pad to put beside my keyboard. This seemed like the only option that didn't have a keyboard attached. Once i got used to it on the left, it has now become fairly natural to use and i really like the gesturing software that it uses. i think it is almost as fast as using a mouse if not quicker. Battery lasts a very long time and if you use the Logitech software, the icon in your taskbar will show the battery level. The ither nice thing, is that the gestures are also available for the touchpad on my laptop, so that's a plus. This uses a Logitech Unified receiver so it is compatible with some of their keyboards as well and will run off 1 receiver.

Great! Loveit!1 issue though. the install directions don't work as there is a broken link on Logitech's site and I couldn't get the driver. The only way I could get it to install was by using my existing Unified controller software, since I had previously been using another Logitech Unified device.

Good product if you hate clicking mouses, compatible with Windows 7.Battery really lasts after a full charge.Go ahead and buy if you have RSI from clicking mouses.Update======I bought this product in Feb 2016 for around 5,000 bucks from amazon.in. Current price (on 1/10/2016) of 11,300 rupees is outrageous!!!Come on guys, give us customers a break!! Shame on you Logitech/amazon sellers.

This review is based entirely on using the T650 with Linux Mint 17.1. I have no experience using it with either Windows or OSX.Despite Logitech's well-known indifference to and apparent dislike of the Linux/Unix world, they do make some good products, and so I decided to try the T650 based on some early comments from Linux users. I spend most of my time typing, not mousing. I wanted to try a trackpad in the hope that I could do the relatively few mouse-y things I needed without moving my arm too far away from the keyboard.Out of the box, the trackpad came with firmware version 041.000.00033 which allowed it to be used for most gestures under Linux immediately. However, clicking required actually depressing one of the physical microswitches located in the very bottom left and right hand corners. This was awkward and unwieldy. The solution is to update the firmware in the trackpad from the manufacturers site support dot logitech dot com. Unfortunately, this update must be done on a Windows host by first downloading the update, then downloading the Unifying Receiver software and using it (in "advanced" mode) to perform the update. However, once the firmware update is done, the trackpad is much more capable. Most notably, you can tap anywhere to click and tap with two fingers to right click. MUCH nicer and smoother. There's no need to use the physical click switches at all and this makes a huge difference in usability.Nice things:1. Very smooth operation, easy to control, easy to manage. Very similar in feel to a MBP trackpad, but bigger. Easy to configure different swipe patterns, eg three finger swipe to bring up a menu. With only a very light touch required, the pad manages to avoid becoming stained with finger oils after use. I've not had to clean it yet.2. Will likely work great with most Linux distributions, once the firmware is updated. (Will be usable but hamstrung until then).3. It's very low-key in appearance and fits in well with my "all black" developer workstation. It seems well-built and solid. The status LED is subtle and (unlike some devices these days) does not attempt to signal ships foundering off the coast.Bad things:1. The firmware update has apparently been around for some time - why doesn't Logitech ship trackpads with the current firmware on them already? Why did they send me old merchandise?2. The device is advertised as being portable, but there is no slot to store the receiver USB dongle like there is with other Logitech devices. This means it has to be carried separately.3. If you do want to use it in multiple locations with a receiver at each location, be aware that the device can only be paired with one receiver at a time, so you'll have to run the pairing software each time. The alternative is to carry the paired receiver along with the device, but then see #2 above. I can only surmise that the cost of 8 bytes of memory for an additional receiver address would have pushed the product into unprofitability.4. It uses the very-small-and-delicate USB 2.0 mini-B connector, which is known to be an unreliable weak point after a relatively small number of insert/remove cycles. Be careful plugging and unplugging. I mostly just leave it plugged in as it's dedicated to my desktop. If you're mobile all the time, this may be a consideration.5. The battery is not removable. Once it stops accepting a charge, you will either have to keep it connected all the time or throw away the device.Not real green, Logitech.Weird things:1. The device attaches via a USB cable, but this is used -only- for charging the battery. I haven't had the device long enough to test Logitech's claim that the battery lasts for 30 days, but at some point you're going to have to hook it up. From my point of view, it would have been a lot easier to use the USB cable for both data and power like every other normal device, but Logitech seems pretty wedded to their little receiver dongle thingies. For the majority of us that don't have 6 different Logitech devices (or even more than one), the unifying receiver stuff is mostly just annoying hype.2. If you have a mechanical keyboard, the trackpad itself is likely much thinner than the keyboard, meaning you have to move your hand down as well as laterally from the keyboard to access it. I'll be looking for a way to bring the trackpad up to the same height as my keyboard so I can move smoothly between them. This may be as simple as a small block underneath it; not sure yet, suggestions appreciated.Overall, I'm pleased with how this device now operates. I wish Logitech would recognize that the Linux market exists and would lift a corporate pinky finger to expend the small amount of effort it would take to properly support their devices under Linux.

I just brought one yesterday and I'm loving it. So easy to use and navigate through the computer. I'm using it on Windows 8.1 and it makes it much easier to use.

I am loving the Logitech Rechargeable Touchpad T650 with its user-friendly ease of use and many great features. The small size of 5 1/4" width x 5" length, smooth surface, rechargeable battery, very responsive with light-touch to activate gestures, on/off switch, place anywhere to use and sturdy design makes this the perfect touchpad for me. I got this touchpad as my computer mouse stopped working. I thought about a touchscreen monitor, but opted for this touchpad instead as it would be so nice to not have to stretch and fatigue my arm with the actions needed with a touchscreen monitor. The touchpad only needs a very light touch of the fingers to click, slide and navigate the gestures to activate the product features, which is most excellent to keep stress off the fingers. I have a desktop computer with Windows 7 right now, but this touchpad supports Windows 8 when I make the change which is another plus for me. Note a gesture not listed on the Logitech site that I just happen to notice worked to activate the right mouse click is a very light tap of two fingers in the middle of the touchpad. Also, note that a two-handed gesture not listed on the Logitech site that I found useful to highlight is to apply pressure to the left-hand bottom corner of the touchpad with the other hand lightly touch the touchpad with a smooth move of the cursor to highlight, then release the pressure on the touchpad to end highlighting-- after you have finished with copy and paste or drag and drop, to release the highlighted text--place the cursor on the highlighted area then lightly tap anywhere on the touchpad with one finger. Make sure to download the latest version of software for this touchpad to avoid possible glitches. It took me less than a day to get used to using this touchpad, and I find this touchpad superior to a mouse. I highly recommend this rechargeable touchpad and hope this review is helpful to others.Tips for this touchpad's gestures (includes some that I wrote above):(1.) To activate the right mouse click is a very light tap of two fingers in the middle of the touchpad.(2.) A two-handed gesture to highlight is to apply pressure to the left-hand bottom corner of the touchpad and with the other hand lightly touch the touchpad with a smooth move of the cursor to highlight, then release the pressure on the touchpad to end highlighting-- after you have finished with copy and paste or drag and drop, to release the highlighted text--place the cursor on the highlighted area then lightly tap anywhere on the touchpad with one finger.(3.) Download the latest version of software for this touchpad to avoid possible glitches.(4.) Use the on/off switch on the top right side of touchpad to turn off when not in use for a long period of time to save the rechargeable battery.
