First of all the product does what it is supposed to do. It shrinks as expected, has a strong adhesive, and is fairly abrasion resistant once cool. I have 2 issues with the product as received. 1. The plastic box was deformed and the hinged side of the lid didn't stay together. I didn't take that into account in my rating because I didn't buy it because of the box.2. The product label on the packaging is misleading about the inner diameter of the tubes. Thinking something didn't look right I decided to check the diameters with a set of metric gauges. Below are the measured inside diameters, measured in millimeters with an accuracy of 1/10 mm. Fractions of an inch will be rounded to 1/32 of an inch to ensure the tube will slide over anything of this size. )7.5mm (9/32")8.5mm (5/16")10.5mm (3/8) Hope you find this helpful.
