Excellent choice
Size: silicone wire 40ft, Color: Yellow

Solders nice, extremely flexible maybe too flexible
Size: silicone wire red 20ft and black 20ft, Color: Red and Black
The wire solders very nicely. It's very flexible, perhaps a little too flexible. I used this wire in a couple speaker building projects. I like to put the wire in a drill and twist the wires together, it's a nice look and helps with wire management. The too flexible part makes it so the wire doesn't stay tightly twisted. To remedy that I use heat shrink at either end to at least keep the wires somewhat together.

Quality, heat resistant silicone wire for my heating coil wine bottle cutting project. I didn’t need very much, but provided me the best price and option. No regrets.

Loong jumper test cables.
Size: silicone wire red 25ft and black 25ft, Color: Red and Black
Over-kill makes nice tools. This is good tinned fine stranded wire with quality silicone insulation. Five-star stuff, without buying some expensive large quantity minimum from a high-end wire manufacturer.
