A little overpriced, but it works well. Definitely NOT for gaming, but it works perfectly for getting work done. Appears to be plastic all around, not too sensitive, but very, very quiet. I was actually showing a friend something on my Mac and they didn't realize I use even using it, they thought I was controlling my computer with my mind lol! If this item was dropped on a solid surface it would probably explode into pieces, but other than that, it works well! Last thing, the battery life is great!
