Key board not responsive enough adds periods

I was so disappointed in this product. I was excited with it's functionality of the screen and a different color than black, along with the choices of colors of the keyboard. Unfortunately it's not as responsive as my fingers and misses words / letters and then it randomly adds periods and adds spaces. So frustrating. I didn't use it before I went out of town so I was stuck with it for a few days, drove me crazy!
