good shrink

### ⭐⭐⭐⭐ They work fairly well, and they do the job well.
*by M***D on November 14, 2023*

I was really excited to purchase these, and start putting them on ALL of the dozens and dozens of charging cables, cords, etc. They are thick and heavy duty, but are able to stretch some in order to fit it over the end a given cable (example, the lightning cords for Apple and the USB-C cords that seem to be getting more popular). However, my only gripe (and I'm really not sure if this is the manufacturer's "fault"), but it was kind of annoying that every size was either too small or too big. The sizes that had the most pieces were definitely too small, and I literally spent hours trying to stretch/push/pull/wiggle them on to the lightning cords. I was successful 2 out of 5 times before I gave up (2 tore before I was able to get them completely over the head/end of the cable, and 1 I just finally gave up on because there was no way it was going to work); I wound up using a larger size (I think 8mm?), which of course, was the size that had the least amount of pieces. I was worried that the larger size would not shrink enough, but it seems to have worked; not the nicest, cleanest, neatest looking, but it worked). The "glue" on the inside (I guess the part that makes it waterproof) tended to leak out the ends and make a little gooey mess on each end, but nothing major or disasterous. The 2 smaller sizes I was successful in stretching (6mm I think?), took forever to get over the ends, but once I was successful and applied heat, they made a great seal, no mess, and looked picture perfect; however, I just couldn't do it anymore, my fingers were sore and raw, and I couldn't even close my hand when I finally gave up. The 8mm size went right on, zero resistence, but once they were shrunk they tended to leak the glue and goop up on each end, and I'm not positive that they shrunk down nice and tight like the 6mm. Once cooled/dry, they did not move at all, so they seem to have worked. Bottom line, they do the job well, and they have saved many, many cords from early fraying/breakage (my kids used to go through charging cables every couple of months, no matter how gentle they swear they are with the cords, but they have not broken or frayed any cord since I reinforced them with this heat shrink tubing. I would buy again, but would hope to see that they have a different size; either way though, I would still definitely buy again if/when I need more.
