This product is great. It comes in its own dispensable box which helps you keep track of the tubing. The tubing is very elastic and also durable. It's works well with the heat and takes about under a minute to really secure. And the lasting effect is really strong. Great product great price thank you

Works exactly as it should and a little adhesive oozes out the end when fully shrunken, giving you confidence that the weatherproof seal has been achieved.The plastic container is better than most but still flimsy as is typical for these sorts of things but the case in no way affects how well the actual heat shrink tubing works.Tip - get a butane torch for shrinking tubing instead of using a lighter and your heat shrink will have less discoloration and charring.

I bought these to heat shrink them around various 1/8” steel rods that I use to make custom holders for my tools around my workbench. I don’t want metal on metal when it comes to hanging/storing my tools. So I cut a few in half and shrunk them around the steel rods to add cushion and protection for my tools. The adhesive is strong and luckily when it cools it’s no longer sticky which I was afraid it would be. The more the tube is allowed to shrink, the thicker the result is and I wanted a nice thick buffer between my tools and the steel holders. I thought it would leave a sticky residue but rest assured it does not! Great amount and variety of sizes for the price!
It's a me, Mario!

Wanted some shrink tube that was colored and heat activated glue. Worked very well for what i needed to do. Has a really good shrink rate and sturdy glue. It's nice having more than one color option. Will buy again

I was pleasantly surprised by the wall thickness of these heat shrink tube pieces. They have a very good shrink ratio that allows for a well conformed finished result around the wire splice or crimped connection.

This is a great assortment of the most common sizes of shrink tubing. I really appreciate how it is kept organized in a handy plastic box. They seem to work just as good as the expensive name brand ones but at a much more economical price point. I will definitely be ordering more very soon.

This review evaluates the “1/8-IN Adhesive Lined Waterproof Marine Grade 3:1 Ratio Red Heat Shrink Tubing (50 Feet)” made by DOWIRE.The product was well protected in its packaging and comes in a cardboard box. What’s in the box: one (1) fifty (50) foot roll of 1/8-in adhesive lined waterproof marine grade 3:1 ratio red heat shrink tubing.First impressions: The box case comes with a generous amount of heat shrink tubing by the foot so you can cut EXACTLY what you need without waste. The thickness of the shrink sleeve is average for heat shrink tubing (medium duty) and the length is standard for repairs. I tested a sleeve by performing a typical hot-soldered electrical wire joint. I slid the heat shrink tube over the joint and applied heat to it with a 300W heat gun. The heat shrink tubing shrank evenly and quickly yielding a tight, protected joint. The tubing held firm and wasn’t able to move on the joint. A water-resistant sealant oozed out of the end making the joint waterproof.Cost-effectiveness and value: I was impressed with the quality of this product; it worked well, comes with a generous portion, and is neatly stored in a cardboard box. At a current price of $27.99 ($0.56 per foot), I feel that this is great value for the quality and amount delivered.In summary: The “1/8-IN Adhesive Lined Waterproof Marine Grade 3:1 Ratio Red Heat Shrink Tubing (50 Feet)” made by DOWIRE is a quality product that works well and is fairly priced. I would recommend this product without reservation.Pros 👍:✔ Good quality.✔ Good thickness, size, and length.✔ Comes in a 50ft roll so you can cut EXACTLY what you need without waste.✔ Even and quick shrink ability (3:1).✔ Comes in a storage box.✔ Good electrical isolation protection.✔ Waterproof adhesive sealant.✔ Great price.Cons👎:✘ None.This review evaluates the “1/8-IN Adhesive Lined Waterproof Marine Grade 3:1 Ratio Red Heat Shrink Tubing (50 Feet)” made by DOWIRE.The product was well protected in its packaging and comes in a cardboard box.
