Heat Shrink Solder Butt Connectors Kit

Let's work on building good connections!!

Great quality product, highly recommend the seller, arrived perfectly.

It arrived broken, everything fell out, I don't know if everything even arrived.

They look good although they are a bit small....

The seller is a fraud. I ordered and paid for 608 pieces of heat-shrinkable adhesive connectors, but the seller only sent 100 pieces of heat-shrinkable adhesive connectors and over 400 pieces of heat-shrinkable tubes that I did not order.

Looks great and delivered fast

Typical of a lot of listings here, the pictures on listing are inaccurate, the larger picture indicates the box full of connectors, but the reality is the smaller pictures underneath show the details and the box is nearly 50% full of short pieces of heat shrink tubing

The product arrived quickly and in good condition 👍

Perfect!

It arrived as shown in the photos you use; they will be the red ones and the white ones because the others are thick.

I use them for my soldering work; they are great for small spaces that need to be soldered. I recommend these terminals as they are very practical for small projects.
