For those who have to join wires together will realize how good this idea is.

This is a great product idea.

Nice. I'm sold.

That's Awesome!

Not for use in high heat environments?
Somebody is going to make a mint on these. Great idea.

Would have been amazing when I still worked at Texas Instruments back in the 90's.

Awesome, but transparent tubing? I'd be scared of touching it, 'cause what if the tubing has chafed off and the bare wire is exposed? You wouldn't know.

Telstra could use a few billion of them to fix their copper network. Should work better than chewing gum, rubber bands, twist ties, zip ties and silicone.

Duct tape. You forgot duct tape.

Found these on Amazon awhile back while modding my 3D printer and, since I've never really done much soldering, these seemed like a cool idea and they work great.

After watching the trailer for Super Drags I find watching this video not weird at all, nope, no sireee not at all.

Sure wish these had been around when I spent hours wiring up a new fuse block in my old VW, in 20-something degree temperatures. Could have been done in 20 minutes, rather than 3-4 hours.

So, once you've finished, slide some opaque heat shrink over it. No biggie.

Everything old is new again?

We were using these in the late 90's doing server installs at telecom co-los and I'm sure they were old tech by then as well.

Ol' Summit... right down the street here.
