Mark B. –
Pros: -Slim Design -Great Range with no mouse curser skips -Lighweight -Low profile keys, with perfect tension -Easy to hand it over to other family members in the room -Works great with Windows 7 -Eliminates having a separate keyboard and mouse Cons: -No Backlighting, this would have been worth reduced battery life Overall Review: I have been waiting for this Keyboard since Christmas. Holding out for the Perfect HTPC interface in my living room. Finally it arrived and the wait was well worth it. I could at last smash my old broken wireless keyboard and mouse on the pavement outside! I highly recommend this to anyone that hates clutter in the living room.

Pros: I. Wireless A. Reduced cord clutter. B. Increased maximum distance from connecting device makes use in a wider range of conditions feasible, such as with a large screen. II. Batteries Included No need to purchase batteries at the onset. Will use some rechargeables after these alkalines are depleted however. III. Touch Pad A. Quieter and less intrusive/cumbersome than a mouse. B. No flat surface needed to use mouse functions. IV. Compact All-In-One design A. Since mouse functions and keyboard functions are on one contiguous unit, nothing gets separated or lost. B. Uses only one USB slot for touchpad and keyboard connectivity. B. Small size, and light weight gives a nimble and convenient feel. Easy to lay back with this unit in one’s lap and surf away. V. Short Stroke Keys Similar to laptop keys, these keys move down a shorter distance from released to pressed positions. If you like that feel, you’ll like these. Cons: I. Non-standard Key Placement Some keyboard functions such as arrow keys, home, delete and page up/down aren’t where you’d find them on a standard keyboard. Until one is made familiar with this arrangement, expect to trip over one’s own fingers a few times. III. No Keypad. As with most laptops, there is no keypad to the right. II. Touchpad Double-Click Sensitivity Way Too High A. The minimum time between two consecutive taps required for them to register as a double-click is quite high – often, two independent clicks, such as tapping to select a screen object into scope, then placing one’s finger on the pad again to move the cursor elsewhere, will register as a double-click on the object. This is the biggest issue with this product. III. Construction Could be made with greater rigidity. Flexes if you try to twist in with your hands. May be intentional. Overall Review: Counterpoints to Points Above: I. Non-Standard Key Arrangement – There are many larger bulkier keyboards that also sport non-standard key arrangements. – With use, one will eventually become adapt to the arrangement of any keyboard. II. Construction – May have been made intentionally flexible to enhance durability in less than ideal conditions. Summary ———- The concept is marvelous. I’ve always wanted short-stroke keys and a touchpad for my PC. And wirelessly to boot. That’s not very easy to find. The biggest issue with this product is the touchpad double-click sensitivity. At best, it’s very annoying unless you slow your rate a bit to alleviate the issue. At worst this issue is potentially costly if a dire mistake is made causing the misplacement or deletion of a large amount of data. It should really be fixed.

Pros: Nice compact size. Works on my Windows 7 HTPC in the living room up to 8 feet away with no lagging. Real nice that there is an on off switch, this saves the batteries. Good looking also. Cons: The touchpad is tad on the weak side as far as tapping to open something, but when used for moving the cursor, it works great. The buttons work fine also, as do all the keys. Those who put down as a con, that there is no numeric keypad with numlock etc, need to lighten up, if you read the specs, and / or just look at the pictures, you will see that there is no numeric keypad so why do you put that down as a con? Overall Review: For the price, this is a good little, simple, compact wireless keyboard that works great in the living room or anywhere elas you want to use it.

Pros: Small, lightweight, great touchpad, and takes standard AA batteries. USB dongle is tiny. Win7 stock drivers run the keyboard/touchpad with no separate software/driver installation needed. Great value. Cons: The tiny right shift button is very difficult to use. The up arrow takes half the real estate that a normal size shift button would use.

Pros: under $30. it is good looking lightweight. on/off switch. tile keys.ez install Cons: on/off switch a little stiff Overall Review: would buy another if on sale

Pros: Works well with Smart TV stick. Trackpad works well. Size is just about right. Has on/off switch. Has RF dongle extender. Range is very good. Cons: Haven’t really run into any so far, as Logitech is pretty honest about what you get. Keyboard does have more of a “plasticy” feel than their other keyboard products, but it still feels sturdier than most of the other mini keyboards I have tried. Overall Review: I got this to work with an MK 808 Android Smart TV stick I purchased. It works very well, the keyboard is true, feels great, and types well and accurately. The track pad is precise, though not very good for gaming. I wouldn’t hesitate to recommend this to anyone wanting a good keyboard for a Smart TV setup or HTPC.

Pros: 1. Logitech generally has good quality products. This is the second one of these Keyboards I have purchased and both work well overall. 2. Full keyboard + Trackpad and media buttons all work well. I particularly like the “Left-click” button on the left side of the keyboard so I can navigate the desktop while standing without moving my hands around. 3. Cost – I found my first one for under $30 on special and my second one for just over that. 4. Power efficiency is terrific. We make sure to switch it off when the HTPC is not in use (Pretty much only at night) and in almost a year we have yet to replace the AA batteries that came with it. 5. If you use other Logitech devices, the USB wireless dongle that comes with this can be used to sync a bunch at a time, minimizing dongle clutter. 6. Lightweight – very comfortably held and light but not flimsy Cons: My only real gripe with the keyboard is the 2.4Ghz signal is easily interrupted. Even with direct Line-Of-Sight the signal can be stuttered if you have lots of wireless signals in that band or the dongle is too close to the HTPC case. Logitech provides an extender to move the dongle about 2 inches from the USB port, but that defeats the idea of having a dongle flush with the HTPC and I constantly worry about it breaking off due to incidental contact. I removed an EGG as it really hurts the functionality of the device in a living room. I have the dongle attached to a USB extender cable and completely away from the housing, but like I said, I want the HTPC to be tucked away and having to add a cable for single continuity is cluttered and an eyesore. For the price, I cannot really complain too much, hence, a single egg. Overall Review: A note to Logitech: This product would be essentially perfect at this pricepoint if the signal issue was not a problem. Perhaps a bluetooth version of this keyboard would be better, or a 5Ghz band perhaps. Ideally I don’t want to have to configure anything to get the signal right and I would be willing to pay a little more to make sure. Otherwise – strong product at this price.
