Even connecting short wires is accomplished
This is a must have to electricians and anyone who works with electrical wires. You just connect the two wires at the end and then just heat the connector. So say for instant you had cut too much of the wire and can't wind them together, this allows a clean connection to happen.
Thank you for your feedback

4.0 out of 5 stars Significantly cheaper than buying locally if you need more than 16 connectors!!!
Reviewed in the United States on September 11, 2023
This can of 200 cost about the same as 2 packs of 8 at my local auto-parts stores and seem to be of the same or better quality depending on which parts store I get them at.

As claimed, the adhesive does not run, it just melts & stays in place!

inside diameter of the barrel measures 0.071", large enough for 15 gauge wire, and correctly sized 14ga solid wire (0.0641"), though all of the 14ga solid wire I have is oversized to about 0.072" - 0.074" and flat out does not fit - a non-issue since these are spec'd only for 22ga-16ga.

Only negatives I found are:
1> the copper crimp cylinder is tinned... (extremely minor) since it's being crimped instead of soldered, I would prefer bare copper for a copper>copper connection instead of copper>tin>copper.
2> Slight length wise shrinkage when using 22ga wire on both ends, of about 1/32" to 1/16" - but zero length wise shrinkage on 20, 18, or 16ga wires.
