This Logitech set was purchased with my laptop. I have used it a couple of times, but for the most part it is unused. It was unwise to buy it - until I purchased a desktop - now I use it all of the time. I love the freedom of no cords. The mouse is the perfect size, and flows easily across the desk. They keyboard is comfortable and I have had no problem with pain from using it. It works great, and it looks great. Logitech is a familiar brand that is noted with quality, a brand I trust and a brand that I will deal with more in the future!
There are very few times when I experience a delay in what I am typing, or the movement of the mouse. I love the shortcuts on the keyboard, although they were a bit difficult to program.There are sometimes when I am using it when it stops working effectively, and there is a need to reset it. This was difficult to determine and follow through in the beginning it took me a while to realise that I needed to use the reset buttons in a specefic format. Now though, that I have this knowledge, it rarely happens, but when it does I am prepared.
