I bought this product because my dog loves being outside but the heat is just to much for his dark fur. I have had no problems as far as tearing on the cover. However, the zip ties that came with the cover broke the next day. I then bought thicker ones.... but they broke days later. I then looked for the biggest zip ties I could fine.... they broke a week later. I then decided to go with little bungee cables.... yeah that didn't last either. I ended up going to the hardware store and found these thick rubber bungee cords.... those finally worked! They are pricey but its better than having to replace ties all the time. But my dog loves the shade now!UPDATE: We ended up using metal wire after the rubber bungee cables finally got dry rot and snapped. The cover is finally starting to tear up after many years of having it. I might replace it in the future.I have a 10x10 heavy duty pin. The SunBlock looked too small but with two people pulling each end tight it fits the kennel great! I know it works because we live in central Texas and the grass stays green in kennel. I gave it four stars only because the ties that comes with the SunBlock break but UV ties from Home Depot did the job.It worked out great for my needs. I added it to a metal dog kennel to have a closed in run for my backyard chicken coop.They are happy to free range a little more!Tarp is great, fits the run nicely. The plastic zip ties seemed to be old and brittle. Broke multiple just attaching them, then the wind broke the rest and had to buy metallic ones.I am surprised at how durable this cover is as it has held up all winter to serious wind, snow, and ice. The ties that came with it are junk and broke with the first gust of wind but I replaced with small bungees and they are doing much better. I use this over a kennel for my chicken run to keep them safe from hawks.This is great with exception to the cheap mostly broken plastic zip ties. They do not work in any type of weather. Good price however for the tarp itself. Easy install.When you see this on amazon it looks like the kennel and top come together very deceivingthe top is great, but the dog kennel that is meant for is terribleokLo que llegó es solo la lona es un engaño está venta, no la compren, me siento defraudado, deberian sacar solo la imagen de la lona.
