I'm a radio broadcast engineer and find myself making cables for various equipment as parts are either no longer manufactured or are just difficult to get due to the idiotic supply chain issues. So I bought some cable here on Best Buy, bought the end cable lugs, again here on Best Buy, and also got this set of shrink tubing to dress up the cable ends.It's a nice set with a great variety of sizes. The plastic carry cause is good enough quality where it does not come apart after a couple of uses. I've uses different sizes for various projects so far and the tubing shrinks up evenly when heat is applied. I've done 3 transmitter repairs and did a home cabling project and so far so good.It's a good value set.
