Simplicity

They do their job. The connection looks solid and everything is protected. Just takes a little extra time.

I've used these before and am now ordering to replenish my stock. I like the soldering of the wires much better than crimping.

These have become standard

These have become standard components in projects. It’s the convenience of making three functions at once: a tight, shrink seal; an easy to solder a tight inline electrical connection; and third another shrink for structure support. Plus transparent shrink to observe process

Thanks for the awesome feedback! We’re glad these have become a go-to in your projects.
