300 PCS 3:1 Ratio Heat Shrink Tubing Kit, 5 Sizes (Diameter): 1/8, 1/4, 3/16, 3/8, 1/2 Inch, Electric Wire Cable Wrap Assortment Electric Insulation Heat Shrink Tube Kit with Box (Black & Red)

This kit is great as it has most of the sizes you will probably need. The tubes shrink as expected and overall seem to be of the same quality of other shrink tubing I have used in the past. The case is great with easy organization of the different sizes. And with the large quantity, you most likely will be set for quite sometime, unless you are a regular user of this tubing.

I’m rewiring my entire 95 Miata for a standalone ECU and I chose this kit to take me along the way. I use the small ones over crimps and the large ones for the braided loom. I’ve just finished and it looks great. These shrink down quite a bit and after they cool they are nice and hard, so as to hold the connection tightly. Only thing I recommend if you’re using the braided loom is to throw a piece of electric tape on the end of the loom (underneath where the shrink wrap goes) so that the loom doesn’t pull out from under the shrink wrap later on.

This is OK. It shrinks like it should when light to moderate hot air is applied. I would NOT recommend using a lighter or open flame to shrink this tubing. Use low to moderate heat applied from 3-6” away. The cons: lettering is applied to the tubing and noticeable when using RED. The wall thickness is less than some other brands available. Regardless of the cons, this product does what the tin advertises. It shrinks when you apply low to moderate heat, comes in various diameters, the included divided box it comes in is nice and the price is fair. This seems ideal for light to moderate duty hobby work and the occasional automotive project. It is not water tight but should offer some short-term protection against the elements (situationally dependent, of course). It a bad purchase and the price was reasonable. If you are realistic with your expectations and understand it’s limitations, this could be just fine for you.

Excellent assortment at a reasonable price. I needed 10 of the largest size to put on my new Nylon garage door roller shafts to make as quiet as possible. Perfect fit and I still have 10 more (as well as all the other sizes which will be handy in the future). This was the best price I could find for what I needed.

Worked great

Any size you want is there

If you're making cables and want a good clean finish, this set gives you plenty of tubing for most every cable size. Used this extensively with great results in my car audio install.

For most of us, this is a lifetime supply for cheap. Does what it is supposed to do. Good size assortment and I like having two colors. Any heat gun will work fine, but don't expect a hair drier to be a reasonable substitute.
