One of my better purchases. This has been in use for 10 months now, (including one winter) and has done exceptional in performance at all levels, including even high winds, no grommet tearing. I was so happy with its performance that I bought a second one a few weeks ago, and will install it, beside the current one to lengthen the available shade for events.Great tarp i use it to cover my rv no complaintsProblem is I let it sit in the box for 5 weeks before inspecting. My bad. Then I discovered the tarp is 16 mil not the descriptive 18 mil. Their bad. Let’s hope not a problem in which case; No bad. ?This is the second tarp I’ve bought from this manufacturer/company. The first lasted about a year and the second one hasn’t even lasted one year. The material is semi porous in spots, the seams rip away from the main part of the tarp and the tarp overall all becomes weak. For the money I expected better.UPDATE: The manufacture contacted me and after I sent them a few pictures of the tarp, they sent out a new tarp. They didn't have the 18mil in stock so they sent out the 16mil. The manufacture does stand behind their product.I vacillated on whether to spend this much money on a tarp, and if the additional thickness was worth it. Bottom line, I think it is.The tarp fabric is superior. Heavy and tough. No question it will survive the elements in Virginia. Two nibbles the manufacturer should fix:- The tie-down rings were partly rusted out of the box. They should be stainless not chrome. An easy fix if necessary a year or so from now.- One of the grommets came apart. Also, an easy fix if necessary. Anyone who uses tarps should probably have a grommet kit anyway. They are cheap.Absolutely would buy again.Decent tarp, but there were errors in stitching and grommets were haphazard and a few extra holes punched for grommets by accident, one of which was along the edge. This was probably a factory second. Would be excellent if quality control was better. I will update if it doesn't last any longer than the cheaper thinner tarps.I have only had this for a couple of weeks now and it's held up just fine so far. It is being used to cover a 12 foot trailer and sees all day of sun.It holds water in depressions, so the waterproof aspect is definitely there! I'm a little bit worried about the seam in the middle that holds the two pieces of tarp together (in order to make the larger 12 x 24 tarps, they seem to have simply adhered together two 6ft wide segments. Additionally, it's being held down with bungee straps and a little bit of 'pull' on one of the eye lets caused separation from the tarp.Time will tell how it holds up to the elements and repeated use.Would never buy again. Cheap materials used. We usually replace every 2yrs. This barely lasted 6 months. ?
