I recently saw on TV about an ad about cholesterol and it scared me so I went into a store (Boots to be specific) and they refused to test me because I'm 16 years old not 18 yet. Because I started to worry and develop anxiety of it (it's in my genetics) I saw this product after searching "cholesterol test." I spent £4 on the product which was actually cheaper than Boots when it came I was baffled and had no clue how to use it after reading the instructions I still didn't know so I checked a video on YouTube and knew how to use it. Got my results (3.3) and now I know I have a great cholesterol level and I know I have no risks of problems. In summary I would recommend this product 100% but please do some research before you get the item (to see if you understand how to use it) I now also know why this product got bad reviews on Amazon UK mainly because they didn't know how to use it which I think is completely unfair. Great Product!
