3M Heat Shrink Tubing FP-301-Color Assortment Kit, 1 Kit with 133 Tubes, One Size

I bought 3 brands of shrink tube in Amazon, two around 10$ and this 3m 150$ !!!! Three things keep in mind: 1- adhesive material inside (like glue which comes out when heated to secure it and no humidity goes inside. 2- the thickness of the material itself 3- the amount of glue that comes out This so called 3m brand has no glue inside and thin (I classified them thin and thick cuz I only saw two standard thickness) Other brands I tried “”wirefy”” which is also thin and has little amount of glue inside “”chines”” The only brand which I saw close to an original shrink tube that came with an expensive light I have was eventronic, this brand seems to be German but made in China. Has thick material of glue and the material itself is thick. Save your money I can’t believe I actually paid 150$ for this. The others around 10$ to 14$ range with similar quantity. Actually this 3m box was even the least of them.

Great product!

If you are using this for automotive or outdoor wiring repair don't buy this. It has no sealing adhesive inside so it will not make a long lasting repair. Expected more from an expensive kit from 3M.

I am always using these on all the electrical work I do and they are a good product

Great product
