How to turn your tv into a large screen for your computer
Using a HDMI cord, my small computer screen exploded on my TV, enabling me to see clearly and do spreadsheets and play midi notation with out squinting. The music sound was also using the TV speakers instead of the computer speaker. Yes, using a boom speaker I can transfer the sound , but speakers on the TV were automatically turned on. It was fun.

Stay away like this keyboard stays away from solid connection
This is a terrible set. Vastly overpriced for something that doesn’t even work. The keyboard misses every other character and you just cannot type at all. Connectivity loss every couple seconds. Junk set. Crazy price

Needed a replacement
I needed to replace my 6 year old keyboard. This was the same thing so I felt comfortable with it.

I have bought 2 of these and they are great however twice now I have """""**(**& up both the USB connector. This is the only USB stick that can be used with this combo so now on my 3rd keyboard/ mouse set. They should it maybe consider universal USB so if this happens then at least the keyboard and mouse can be functional. I have opted with another brand for now. If not well, where can i return my last 2 purchases cause they are brand new and useless. :( to the manufacturer?

I've owned a number of wireless kb/mice. While this one isn't the best with regard to functionality, it is by far, the best value. I use this on/around my coffee table and couch, to control my desktop computer (about 8 feet away); it works great! While there can be a signal detection issue with the mouse, it's due to it being too far back on the coffee table, blocking the signal. It's more compact than most keyboards, with no separation between the main keys, arrow keys and number pad. I've had it for a while now and only wish I would have purchased it sooner. Pros: Extremely light weight. Very low battery consumption. Compact. Good signal, no connection problems (if no major obstructions in the way). Cons: Mouse scroll wheel button is too easy to accidentally press when scrolling. Keyboard seems to have a power saving mode (if the keyboard isn't used for a while, the first key press will be ignored/used to "wake" the keyboard. This is a minor inconvenience and saves your batteries, so in a way, it's actually a pro. To unlock windows, I simply type the first key of my password twice. The first press "wakes" the keyboard and the second press begins typing. Overall, great value!

It's a wireless mouse a keyboard set. The product itself has some pros and cons but overall is great. The mouse and keyboard work exactly as expected, in that they're able to type and click things with easy. A huge pro for me is that they actually share a wireless adapter so I don't have to waste 2 USB slots, 1 will suffice. It also makes it easier when relocating them as there less pieces to lose. The mouse is a decent weight as well and both are sleek-ish looking. The cons are that they use two different batteries. The keyboard I believe uses a single AA (Pro for 1 battery) where the mouse uses 2 AAA (Normal for 2 batteries but con that they're not the same battery size as the keyboard). The keyboard also has no lights so it's impossible to tell before typing if Num/Scroll/Caps Lock is on. It's also hard to tell of the keyboard is connected because there's no lights. I think the largest con with the keyboard is that there is no off switch so you'll be draining that battery even when not in use. Overall I'd say it's worth the price though and if I needed to I'd buy it again.

This is a steal of a deal on amazon to get an Ms branded key and mouse wireless for under 30$ at the time of writing One dongle services both keys and mouse. So saves you from using up two USB ports. The keys feel soft like a laptop. Its obviously not a mech switch board. Its a good budget wireless setup that generally works for most people. The mouse is fairly light weight so if you are one that prefer a specific weighted mouse then this isnt for you . The wireless dongle works without glitch for both mouse and keyboard at an even far distance so if your pc setup is a few meters away , such as in a HTPC setup on your tv, this will handle it. I bought and trashed no name brands that are sold here that simply doesn't work if youre even 60cm away from the dongle!!! There is not much to comment negatively because of the price tag and the quality. Good value.

The microsoft mouse and keyboard works great. Really easy to set up. It only takes up one outlet on the back on my computer. I am seated about 12 feet from my computer on my couch. I also have a Sewell box which sends my computer monitor screen onto my 50 " tv screen. Now I can relax on the couch and use the keyboard and mouse to control my computer while I watch it on my tv. It's great to be able to control youtube ,netflix or anything else I want to look at on the computer, but be able to see it on my tv while sitting on my couch.
