Huge Set With Everything I Need
This kit comes with a lot of connectors â more than enough to last me for years. It really feels like it has just about every size I could need, so itâs nice knowing Iâve always got backups on hand when I run into a project.Iâve already used a handful and they do the job. I will say that having a good crimping tool makes a big difference with these, and thatâs the next thing Iâll probably invest in. Even so, itâs been great having such a variety right at my fingertips instead of having to run out to the store every time I need a different style or size.For anyone doing automotive wiring or just general electrical work around the house, this set covers a lot of bases. Itâs organized, easy to dig into, and gives me peace of mind knowing I wonât run short any time soon. Good quality and price is great for that many.

A Great Value Connector Kit for All My Wiring Needs
I recently purchased this heat shrink butt wire connectors kit, and Iâm really pleased with it. The quality of the connectors feels solid, as theyâre made from tinned red copper that provides a snug fit. The wires I’ve crimped on have proved a reliable connection on my automotive and household projects. Theyâre easy to work with, crimp securely, and the length of the shrink tubing is just right for a tight seal. The variety of sizes is convenient so I’m no longer digging in a ziplock bag of random connectors that had spilled ages ago. I’ve not tried any of these on a boat or similar wet application, so I can’t really say how water-resistant the connectors are. As a super duper extra bonus, I now have all the sizes and quantities I need to tackle different tasks without needing to make unnecessary trips to the store. For the price, this kit offers fantastic value for the money, and Iâm glad to have it on hand for future projects!

Meter the Matter – There’ll be Less Splatter
Nice set of terminal connectors. The heat shrink works very well, they crimp on nicely. I took a file to them and they are indeed copper coated with a healthy portion of tin. The set includes ring terminals for 3/8″ terminals in all 3 flavors. Some kits don’t and my head will occasionally explode when I’m trying to drill a 3/8″ hole through a 5/16″ ring terminal. I like this set – I’ll be cleaning up less brain matter.7 Super Novas for The YUMKIYI 180pcs Heat Shrink Terminal Connectors Kit~ Thanks for Reading â Have an Incredible Life! ~

Solid Grip and Great Value â Using for Household Projects (Though Not Sure About Compliance)
I bought this 515-piece terminal connector set mostly for the yellow 10-12 gauge connectors, which Iâve been using in a few household electrical projects. I havenât tested every piece in the kit yetâjust the yellow and some of the blue onesâbut the quality has really impressed me so far.They crimp down firmly and hold tightâno slipping or weak connections. They feel sturdy in the hand and lock onto the wire with a rock-solid grip, which is exactly what you want for any wiring job.Now, Iâll be honestâIâm not sure if these are fully code-compliant for permanent household electrical use, so Iâve been using them in less critical applications and small personal projects. But for what I need, theyâre working great.

Its all there
My complaint is quality for price. These are nothing special but cost too much. The current price is $19.90 which I would expect if they had heat shrink ends. As a matter fact I only ordered these because that’s what I had seen pictured. Its possible they added more products after I ordered or I selected the wrong one. A confusing product page isn’t a virtue.

Great value heat shrink terminals!
Packages arrived in a timely manner and as advertised. Terminals are made to a very good quality with thick PVC vinyl coating. Use the 22 gauge terminal two butts twice a wire bundle to a nest thermostat. Terminals react to the heat gun well and heat shrink very well and shrink down to a nice sealed fit. Once all the connections were soldered, a functional check of the thermostat was conducted and found to be satisfactory. These are great terminals to have around any shop and will come in handy for a variety of applications. Great value for the money. Will order again in the future when the supply gets low.
