Review on Foremost Tarp 11216 Reversible Polyethylene by Todd Fernandez

I bought this tarp because the price for 7mil was pretty low. Tarp size 12x16 feet. I typically use 5 mil tarp in the garden to cover furniture and the more expensive 10 mil tarp for outdoor sheds and have had a few tarps over the years. This is NOT 7mil tarp and nowhere on the packaging does it state thickness, which in itself should be a warning sign. A quick check with a micrometer AND calipers and it looks like it's closer to 3 mils (my 5 and 10 mil tarps measured 5 and 10 mils exactly). This confirms all other reviews that mention how weak this tarpaulin is. No wonder it's so cheap, the seller misrepresents the thickness, and Revain needs to do something. I send it back and usually choose the exchange option, I might swap this tarp out for a 12 x 16ft 10 mil tarp from the same supplier (Dry Top) but of course how can I trust what it will cost 10ml. ? I'm only getting a refund because after reading the reviews on their 10M tarp I'm sure it's misrepresented as well.
