innhom 650pcs Heat Shrink Tubing Black Heat Shrink Tube Wire Shrink Wrap Shrinkage Ratio 2:1 Electrical Cable Wire Kit Set Long Lasting Insulation Protection

I wish it had more different sizes. But it's a great thing to use

Needed a variety of shrink tubing sizes for a few wiring projects, and this kit delivered. The assortment is well thought out, with enough pieces in each size to cover multiple jobs. Shrinks evenly with a heat gun, holds tight, and looks clean—no weird melting or uneven spots. The case keeps everything organized, which is a bonus when you're juggling tools mid-project. Not high-end industrial grade, but for DIY repairs, electronics, or vehicle mods, it absolutely does the job. If you need shrink tubing and don’t want to overthink it—this kit’s a win.

I have never owned another brand so I have nothing to compare to but I can definitely say they are dark in color just like the picture, they are durable, come in the most needed sizes for my hobbies and are easy to use. I use a heat gun and the connection seems durable.

This heat shrink tubing kit is a solid buy if you do a lot of basic electrical or DIY work. The assortment of sizes is very useful, and having 650 pieces means you’re unlikely to run out anytime soon. The tubing shrinks evenly with a heat gun and provides good insulation once it’s set. I like that it’s UL approved and feels safe to use for automotive wiring, small electronics, and household projects. Most pieces shrink tightly and hold well over time. That said, the wall thickness isn’t completely consistent across all sizes. Some of the smaller tubes feel thinner than expected, so I wouldn’t rely on them for heavy-duty or high-stress applications without adding extra protection. Pros: • Large assortment of sizes • Shrinks evenly with good insulation • UL approved and safe to use • Excellent value for the quantity Cons: • Thickness varies by size • Not ideal for heavy-duty industrial use Overall, it’s a very good heat shrink kit for DIYers, hobbyists, and light automotive work. Reliable for most everyday needs, just not meant for extreme-duty jobs.

Good 😊 thank

Good value! But the box clips do not seal tightly, which leaves a bulge in the middle center of the lid. Because of this, the tubes arrived all mixed up and out of order 🤣 But that's no big issue. Peace between nations!

These heat shrink tubes are excellent. They come in a wide variety of sizes, and I had no trouble using them on the wires I intended to splice. Although I’m not particularly skilled at soldering, I left some sharp edges, but the tubes didn’t break when they were shrunk. This assurance in the product’s quality gave me great confidence. I used a lighter to shrink them, and fortunately, they didn’t catch fire. For my initial use, I needed the smallest size available, and it shrunk perfectly. Overall, I believe this was a wise purchase, and I anticipate getting a lot of value out of it.
