Good quality at a great price. Seem waterproof after heat shrinking. Good connection. Multiple different sizes for versatility.

Very good price, good quality and the sizes provided met all my needs.Prices are substantially less than most retailers. Well worth the wait for delivery, and to my surprise, much quicker than expected.Thank you

My first time using heat shrink connectors and these worked great. I feel the connection on a wiring harness will last, and is secure with protection.

I recently did a couple of automotive rewiring projects and needed bulk heat shrink connectors in different sizes. This set was inexpensive for the amount you get and they worked great, providing a nice, neat, seemingly solid wire junction with just a little heat application from a heat gun. Only removing a star because the plastic box they come in is super flimsy and the lid broke off almost immediately. You will want a better container to store them in.

Replaced the led light strip on the under side of my 5th wheel rv. The heat shrink butt connectors were easy to use and shrink to make a water tight seal.

works well

For the longest time I was buying the little packs of these as I needed them. Then I thought to myself I am just going to buy a big variety pack. These are great way cheaper than buying in store and its nice having all the generic sizes you'll need. Plus, the connectors are way nicer than the ones you buy in store as well they have the glue that comes out the side when you melt them.

Great product, exactly as described

Makes good connections every time.

De maravilla, sorprendidos en el taller.

Good

Works as intended. Very easy to use, seals up nicely.

Al principio creí que no funcionaba el plástico termoretráctil porque lo estaba intentando encoger con un encendedor. Normalmente el tubín termoretráctil(heat shrink) sí se encoge con un encededor común, pero este es más grueso, entonces al hacerlo con encendedor no funciona, no se encoge y se empieza a derretir y quemar antes de encogerse. Pero ahora que compré una pistola de calor, funciona excelente. :D
