A good Type 43 core that is the correct size and a good value for the cost. No pitting or defects noted. Using these for a 2xFT240-43 9:1 End-Fed, and I can't tell any difference between this one and ones from 'major manufacturers' based on side-by-side comparison in duplicate 9:1's built.

Made a 49:1 balun for an EFHW antenna and from an SWR perspective, it was very close to other cores that I have used, so the material is definitely correct. The shape depicted on the marketing photo is correct, so its a little different that others, but it will work. The price is right as well!

I used this torroid to make an RF choke for an HF radio and it is working well. It has reduced common mode currents and dropped the noise floor down to an acceptable level. Its the right size for many uses such as a transformer for an antenna and priced right at $10 at the time of this review.

I use these magnets to hold tools up on the wall, and for that purpose these work fantastically. They are strong enough magnets to hold up heavy tools and they work well with anything that has a significant amount of ferrous steel on them.I also use these magnets to filter out particles containing iron in my shower water pipe. Because the magnet is monopole magnetic N, it makes the water north magnetic water. Magnetized water is supposedly good for your health and so I decided to use this magnet for that purpose. So far so good.These magnets are perfectly concentric, smoothto the touch and convex on both sides. The outer side is flat. I understand these are used for noise reduction along power cords and or electric components and I'm sure it will work well for that purpose. For my off label uses these magnets also fit the bill. Because of the perfectly round nature, fits around faucets or pipes perfectly. And the magnetism is definitely strong enough.

Regular 240-43 toroid for radio projects.Has beveled outer edges for easier winding of stiff wire.I haven't put it on the VNA yet, so will update this review if I find any surprises.
