It had a bit slow delivery other than that the product is perfect and it came in a nice shipping package protected by bubble wrap and a very rigid box

Product arrived early! Well packaged, all toroids were intact. Would buy from seller again!

These binocular cores arrived on time (when USPS gets involved during the last mile, all bets are off) and were priced okay. I definitely appreciated their availability on Amazon in smallish quantities. I haven't used them yet (isolation transformer for ham radio loop-on-ground antenna), but I am excited at the possibilities. I can't measure the core's exact permeability and I can't even definitively say whether they are even ferrite in a scientific sense, but based on many previous reviews, I expect they are as promised. :)

Experimenting with receive antenna's. This is exactly what I needed to complete my loop on the ground. I will say this. The more wire you can lay out is better. I started with 60 feet and wound up with 180 feet K2LNS

I used in my LOG antenna build as a galvanic isolator. Worked like a champ.

I purchased these to make transmormers for Loop on Ground recieve antennas. They work well for this.

Perfect part to make a loop on the ground transformer.
