I ordered these in an attempt to stop my washing machine from causing LED light bulbs throughout the house from dimming during the agitation cycle. They did not solve this problem. However, I had no problem getting them on the cord and getting them to snap together.

This package does not come with 5 different inner diameters as stated, but only (supposedly) comes with the 4 different inner diameters. But even then, I only received 18 instead of 20 ferrite beads. Here is what I received (from the smallest size to largest size): Seven ferrite beads of 5 mm diameter (none were of 3 mm diameter), Four ferrite beads of 7 mm diameter, Three ferrite beads of 9 mm diameter (I should have received four of these), and Four ferrite beads of 13 mm diameter.It happened to be fine for me that there were no 3 mm diameter ferrite beads as it turns out those would be too small even for my smallest cables. I even only needed six of the 5 mm diameter beads, so it doesn't impact me that I only received seven instead of eight. However, I did need all four of the 9 mm diameter beads and only received three. This package was still useful to me to help me figure out what size ferrite beads I need, but I will be finding a different place to order ferrite beads from in the future.

Effectively blocked so much noise from the electronics that interferes with my wireless connection.

My home stereo speakers were picking up someones ham radio signal, which would play overtop of my music and throughout the day. Reddit pointed me to ferrite beads, and these worked perfectly! I just snapped a few on to some wires, and I haven't heard any "ham" since. Excellent product and value.

i never leave reviews but these worked beautifully for me. i just purchased an sm57 and audient evo 4 and i was getting horrible static on recordings, when my gain was at about 70%. i slapped these on and the static is NOTICEABLY lower, i can turn the gain up to 75 and i would have to focus to try and hear the static

Bought these for my husband because his computer monitor kept turning off every time he stood up. Put these around his monitor cable and problem solved!

I got two packages of these and then started sleuthing the 75 Meter S4 noise floor in my ham shack. Thanks to these clip-on ferrules I've been able to reduce that to about S1, and I can tell where my noise is actually coming from (a laptop power supply. :-( )Being able to easily reposition the beads is a real plus, honestly didn't expect it to help as much as it has! All the different sizes have been very handy, too (from LM400 cable down to the 24 gauge wire pairs on my HT chargers!)
