Quality magnet wire - perfect for building baluns
This BNTECHGO 18 AWG magnet wire is excellent quality and worked perfectly for building a balun for my antenna system. The enameled copper wire is consistently gauged throughout with a smooth, even coating. No thin spots or inconsistencies that would cause issues. The enamel insulation is durable and holds up well to winding around cores without flaking or cracking. The wire is flexible enough to work with easily but maintains its shape once wound. Stripping the enamel when making connections is straightforward with a lighter or scraping. The 18 AWG size is perfect for common balun builds—thick enough to handle power but not so heavy that it's difficult to wind tightly. The copper quality is evident in the wire's consistency and the clean solder connections it makes. For the amount of wire you get, the price is very reasonable. Having a good supply on hand means I can experiment with different balun designs without worrying about running out. The spool keeps everything organized and tangle-free. Whether you're building baluns, transformers, inductors, or other RF components, this is quality magnet wire that performs exactly as it should. Highly recommend for any ham radio or electronics projects!

Good choice for coils
This seems to be very good quality wire. It was malleable and the enamel was rugged. I got no enamel flacking or cracking when winding 1.5 inch coils for ham radio use. Even 180 degree bends were crack free. I'll buy more.
