The price is fair for the quality you get. They crimp well and seal the wires well when heat shank.

This kit pretty much includes any size I would need and comes in a case that seems somewhat sturdier than others.I have used a couple sizes from the kit on a small cargo carrier project I did. Each tube used crimped great (using their tool), shrunk perfectly, and seems pretty weather tight. All that is well and good, but the key is that each electrical connection worked flawlessly.This kit may cost you fractions of a penny more per connector, but you are paying for quality in each one. To me that is well worth a couple dollars more.I would recommend this kit and the crimping tool they make as great companions. The company just needs to put both of these into a nice convenient kit with a space in the box for the crimping tool.

Very good connectors, they crimp and shrink very well used them indoor and outdoor situations no issues. I ran these underground - direct burial and they have lasted over a year for powered speakers.

I used these on some outdoor speakers and this sealed the wires nicely. We will see.how it holds up over time. Easy to use and like the "Jar" they come in.

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.

I’m a huge fan of Wirefy. Easy to use, consistent build quality and I haven’t had a failure yet. The glue inside the heat shrink tubing makes the connection strong and permanent.Dr. M

I have used similar connectors which shrink to seal the wires and ideally also cause a soldered connection, but the insulation around the soldered union tends to break down somewhat thus rendering the end result unacceptable. However, this design is substantially more robust both on the crimped/soldered union and for the shrink plastic. The only complaint is that what's supposed to end up as a soldered connection doesn't appear to be complete. Still, the resulting union is strong, intact and waterproof.

Was soll ich sagen, qualitativ besser als die bei uns auf Arbeit und unsere sind von Normfest.Schließen gut mit dem Kleber ab und lassen sich auch schön krimpen.Für mich ein sehr gutes Produkt ohne Mängel. Schicke Dose im Vorteilspack

Lo usé para unir dos cables de 220V de 1,5 mm en una embarcación. Es robusto y da sensación de estanqueidad a la humedad fiabilidad y durabilidad en la conexión realizada.

Excellent option to RAYCHEM butt splices. These take up a bit space but they do the same thing and are economical for most wire repairs. Used with WIREFY crimper with no failed crimps. No hesitation to buy the heat shrink terminal lugs when needed.
