Quality, multiple sizes, shrink well.
These are great, with multiple sizes. Working on our camper and odds n ends around the house. These came in handy for electrical work. They shrink very well and great quality.

Full saltwater proof on boat trailer
Works really good for my boat trailer, I live in Florida so it’s fully waterproof with the salt water here. Easy to wire I advise to use a heat gun or candle lighter don’t use a torch. Good product

Crazy good product for the cost.
These are crazy good for the cost. They shrink up heat keeping it water tight, crimping the metal wires inside is easy and holds shape without loosening. I would still wrap with electric tape to be double safe.

Good!
Nice heat shrinks and connects the wires well when you clamp. I was looking for these cause the white ones are small and help with the wire size i was dealing with. The heat shrinking works well.

Funcion bien el plástico termoretráctil
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

plutôt pour des gros fils
Il vaut mieux bien insister pour sertir sinon ça ne tient pas.

Really nice set. Quality and good price.
Took a moment to try this and really loved it. Very expensive retail but this set very reasonably priced, easy to use and comes in a convenient case. First time users should practice as I did. Heating the finished repair can be a bit tricky if you haven't done this before. Highly recommend.
