Summary: I am very pleased with this keyboard. The price was better than I could have expected. It is very lightweight, but it doesn't have to be heavy to do what is needed. I bought it to plug into my laptop when writing emails. And that is all I have to do, plug it in. I did not have to download anything. When doing any amount of typing like making a document or writing emails, I do not like the laptop's keyboard nor the flatness.
Summary: after I ordered this keyboard & mouse, I went out and bought a new computer. the new computer came with keyboard and mouse. Instead of returning...I'm going to keep it as a back up. Who knows, I may need it down the road.
