Eventronic 400 Pcs Heat Shrink Tubing Kit-3:1 Ratio Adhesive Lined,Marine Grade Shrink Wrap - Industrial Heat-Shrink Tubing - Black

Great variety of sizes. The case is a little small for how many they packed into it, but not a problem. The adhesive flow is perfect and keeps the wrap in place. The shrinkage is on par for 3:1. They work like they should and seem to be made well.

All heat shrink tubings are the basically same. Apply high temperature via a paint heat gun, the thin plastic shrinks and secures the two objects, usually wires..So, which kit should the user buy? . . . What features should differentiate the endless choices on Amazon?.First, there are no "Consumer Reports" testing on such a common commodity. So, the user can only read the advertisement hypes claiming fantastic durability, longevity, ease of installation, and strength. The reality is that the user can only hope that it will last more than 30 days, the Amazon return limit..The only guides are the 29,209 Amazon user evaluations. On August 5, 2024, there was a cumulation of 97% positives and 3% negatives. The super positives were 79% 5-stars and 14% 4-stars. With such impressive statistics, the buyer is assured that this product has quality construction and components..The second determinant is the variety of size options. The user needs the best fitting. This kit has 12 options with 0.5mm differences. The competing products are limited to seven sizes..The third criteria is price. Nine hundred pieces for $11 are very generous. Compare to the two big box storefronts, the largest sold a 20-piece kit for $21.

This is a nice kit. They shrink great around wires, dont split and have great thickness. It's a nice assortment. They are quite a bit shorter than expected but still worked great and can't complain. Can't beat the price and the case is nice for them bottom be loose and be lost.

These work well. There could be a little more adhesive in my opinion but they still do the job and seem to seal up.

Why did you pick this product vs others?:This is the go to set when you just need a little piece of black heat shrink. They shrink quickly and evenly and are sorted into a nice plastic case. Exactly what I needed at a great price.

I didn't think heat shrink tubing could be this nice to work with - it not only does the job, but the adhesive sealant is a bit of a game changer too as it will help hold things together as well as seal out anything from getting in.Shrinks well, fits tight. Seems like a good product and I'd look to buy it again when I run out.

Received in band new perfect condition. Great quality heat shrink tubing. Also been using this product for years. Very happy with this seller.

UPDATECustomer service reached out to me and fully resolved the issue of the missing pieces. So I added 2 stars.I used one of the thinner wraps to augment worn insulation on a on a #12 wire. It worked fine, better than I expected with my rather wimpy 300W heat gun.ORIGINAL REVIEWThe pack I received had fewer than 170 pieces, not the claimed 200.They are also all a bit shorter than the claimed 3.5 inches or 9cm. None were above 8.5 cm. That may not seem like a big difference, but I bought the longer size because that is what I need.Other than that they look fine, but I have not used any because I may return it. Many of the missing pieces are of the sizes most useful to me.
