CynKen 5pcs 10x140mm Ferrite Rod Bar Loopstick for Radio Antenna Aerial Crystal About 0.4"x5.5"

product i received measured .375"x5" (listed as .4"x5.5"). not a huge concern, but if youre calculating total possible turns for an inductor it does make a difference.

Pretty good quality but the straightness could have been better.If you need to slide the coil that you wind onto the rod make sure to allow a little extra room between the coil form and the rod so you can slide the coil from one end to the other.If you make it too tight and the rod is not straight you may have trouble sliding it all the way. Ask me how I know!!!.

Good product

The product arrived as I expected, and the 3 unbroken rods were pretty much what I expected. However, 2 of the rods were broken into several pieces, some of which are too small for me to use. I planned on cutting most of them into sections anyway, but the fact that 2 of them were broken with jagged edges, only about half of those 2 can actually be used for what I want. But the remaining 3 are ok. It just needs to be packed better. If the delivery driver simply dropped them from waist height onto concrete, they would shatter just like that. Ferrite is extremely brittle. So one star for each of the unbroken ones, no stars for the broken ones.

My favorite AM DXing radio took a tumble and the internal ferrite rod antenna broke in two, rendering it a paperweight. I purchased these rods to repair it and, shockingly, it now receives better than the stock antenna! I recommend these ferrite rods to any AM/MW radio enthusiast who needs to make such repairs.

Arrived fine. Work great in my application, packed well... Of Couse, ol' butterfingers promptly dropped one, and broke it... ferrite doesn't really care in my application, except for picky folks... butt the two ends together, apply shrink tube, then get on with life as if it weren't broken.... also being formed 2 side flat, they won't roll off on ya.... unless you're butterfingers...

I've ordered these ferrite rods many times but this times and they have worked well. However, this time one of the rods arrived shattered. I could take it back and request a refund but that seems like a lot of work for one three dollar rod that's shattered. So, I will probably just use it for a different crystal radio (with a shorted ferrite rod).

I used these for electronics projects and they do what I wanted them too.

Die Lieferung ging schnell und unproblematisch. Die Stäbe wurden lange vor der Zeit geliefert. Leider muss ich aber feststellen, dass sie nicht ganz rund sind. Trotz allem, die Ware ist top in Ordnung.

Ordered a set. Worked for my crystal radios.

All 5 rods packed in one bubble wrap bag, 3/10 rods came snapped (ordered two 5 piece items). Quality of the rods seem OK.
