It was an exceptionally smooth and fast service. What lost 1 star for me was the product itself. I’m not entirely sure what it is that does it, but it almost fees like it lags at times, or is too sensitive perhaps? What happens is somehow the cursor moves somewhere else on the page in the middle of typing, making it quite frustrating when you’re in a hurry, because you kind of have to look for where the error occurred. Also some keys are a little different to traditional keyboard. For example, the Delete button manly serves as a backspace key on the traditional button and there’s no equivalent traditional Delete button. Overall though, it does the job, and feels rather sturdy and not cheaply made. I guess it takes some getting used to.
