Simple instructions - just watch the video on the web - no issues with the lancet, other than quite tough to remove the protective plastic, it required more force than I would have imagined and I thought I was going to break it. I think a lot of issues I read about in the reviews stem from the fact that many people are being a little timid when pricking their fingers, which is natural. This is an accurate blood-type test kit and relatively easy to use. My only error was not realising how much I was bleeding and I had to wash my table cloth afterwards !
