Good value
I have used several of these shrink tubes and they work well. Good value for the price.

OK Quality, Decent Price, Mostly Good - NOT 3:1 ADHESIVE if that is what you were looking for
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.

Every size you’ll ever need
I ordered this kit for two main reasons. First it offers a diversity of different sizes. Sections are rather short but I usually need short sections. If I need something longer I always keep some 3 ft sections of popular sizes. Secondly, this kit is in a nice segregated plastic case, with two different colors ( black and red) included. This is a Good kit. I highly recommend.

Perfect kit for all your shrink tube needs
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.
