Bests & Worsts Reviews from Amazon

It's rare to find a scam like this in Amazon. It's the first time that I've found a scam that is also "Amazon's Choice" (Amazon's Choice for "clear uv film"). The problem is, you won't find out, unless you happen to own a UV meter to test for yourself, so it's a sneaky scam. I tested direct sunlight with the meter and it measured about 7.5. Then I tested the same direct sunlight through this film and it tested about 3.5. You do the math. To show you that the meter works reasonably well, I tested the same sunlight through clear UV glasses and it measured 0.0, as expected the meter does not detect UV radiation through the glasses. Keep in mind that it's not a lab-grade UV meter (you can buy it here for about $37), and that it shows readings in increments of 0.5, so it's not super precise, but I've been using it for months in a variety of circumstances and I haven't seen any unusual readings (other than this allegedly 99% UV blocking film). (Also in the video you'll see the readings change slightly as I was trying, imperfectly, to direct the meter's sensor straight to the autumn sun using my hand.) Amazon should do their own lab tests with this product and if they confirm similar findings, they should ban the sale of the entire manufacturer's product line to unsuspecting consumers. The manufacturer obviously knows that it's selling snake oil.
