Query: Can I give this a Zero?

There is absolutely nothing GOOD to say about this product.First Check Home Cholesterol Test, Two Single Use TestsI followed directions exactly - to the letter. Even using a countdown timer on my cell phone.I got no results. I tried it AGAIN (there are two test strips included). Again, no results at all. Not wrong ones... but nothing at all. And the kit isn't expired, and the testing strips were in their protective envelopes.My wallet is $20 lighter. I have two sore fingers full of holes and a bunch of nasty bloody things to get rid of.Sheesh, they don't even include an alcohol swab in the kit.And they don't bother to recommend that you sterilize your fingers or even wash your hands before you go stabbing yourself full of holes.Shame on you, First Check.
