Shrinks nicely
Impressed with this. The tubing shrinks up quite a lot, which is good. Even the large diameter (approximately 1/4 inch) shrinks down maybe by about 75%. I would buy this again.

It does what the description says it should ;)
Yes, it does what is stated in the description. I have ordered this particular brand from this particular vendor on at least 3-4-occasions, maybe 1/2-dozen. It is made of surprisingly good quality adhesives and polymers (and whatever else those mad lad chemists come up with, I’ll stick to RF engineering myself). The 3:1 heat shrink tubing walls are thick (thicker than SOME brands I have tried but not all) and the adhesive is surprisingly, well, adhesive. Once the thick adhesive lines tubing cools about 20-30-degrees C, it starts to set, quickly. Once it sets it holds/grips with reassuring authority although you can gently reheat the tubing and adjust (slightly) its position. I use a couple of boxes (of various sizes) of 3:1 adhesive heat shrink tubing every couple of months and this specific kit is one I often reorder. The price is always fair and the performance is just what you would expect from adhesive 3:1 heat shrink tubing and is easy to cut and use.

Needed something for emergency splices at work, the multi pack has every size I could need and melts super easy when heated. I haven't had a problem and some of the repairs have been left for months outside in the elements. Great for the price

Used for a low voltage battery project and worked perfectly. Not a high quality product like I've used in the past, but a very good value for suitable uses. Needed only my wife's hair dryer, although it admittedly does run hotter than typical.

Heat shrink tubing works great. Storage case can sometimes have the smaller pieces end up in the wrong compartments, but I purchased for the heat shrink tubing and it's excellent! Have used this tubing in 30+ projects without a single issue
