CBAZY™ Hook up Wire Kit (Stranded Wire Kit) 18 Gauge Flexible Silicone Rubber Electric Wire 6 Colors 16.4 feet Each 18 AWG

Nice wire to work with. Love this stuff, decent size and super flexible.

Good silicone wire, box doubles as a dispenser which is nice, easy to work with

I use it for prototyping and making my projects permanent on prototype PCB’s. The wire also slides nicely into bread boards. If you have been trying to find the right wire for your electronic projects, I am quite sure you will not be disappointed with this wire, as the right wire makes the world of difference to your projects.

Wire has a nice flexible covering. Planning to use on projects.

I didn't test it in any way, so the only review I can give is based on the limited use thus far. I used it on a couple drones and on a couple pi zero rtc mods. Heat wise, it did not shrink or melt which is what you expect from silicone wire. The stretch wasn't bad. While soldering it didn't get in the way. When removing the silicone from the wire, it did stretch a good amount and didn't bounce back a lot. Not a big deal as many brands have the issue. You just need to be more accurate when stripping the wire. Of course, this is thin wire and my general strippers do not go this low or work so well at this size. I just pinch between my nails, so of course that issue is probably of my own creation. However, in one instance it stretched enough to cover the 2mm wire I had already removed the sheathing from. Pinch wise, works pretty well. Its more expensive, but if you can afford it and don't have the most precise tools available, silicone is the way to go. Its forgiving with heat, its great being used around hot items, its very flexible, and versatile in that regard. I still use PVC, but in limited scenarios such as in a board project that has no movement, heat build up, etc.
