Review on Heatshield Products 4-Inch ID x 10-Foot Thermaflect Sleeve Heat Shield Sleeve by Vera Gashi

Poor quality, mustache on edge. The promotional photo shows a very clean edge, but in fact there is a cloth mustache on both edges which makes the sleeve look frayed. I used scissors to cut them. The stitching is really bad and uneven in both direction and stitches. Don't even think you can use that supposed 1/2" heat shield on something 1/2" in diameter. I tried it on a 3/8" battery cable and it barely fit. And don't even think about using it on something with curves as the velcro tends to fall apart. If you use this on something 3/8" or 1/4" it might work. What a waste of money.
