Good quality...less expensive than others
I needed these to help protect sensitive radio devices, but did not want to pay the high price the competition was charging. These are good quality and do the job.

Works as expected
I use this to protect the input of my Siglent spectrum analyzer. While I haven't thoroughly analyzed it, it does not appear to attenuate or alter the input signal in any meaningful way. Adds a nice safety factor to your SA so you don't blow it up with DC input.

Pretty good
Wasn’t expecting a lot for the price but it’s pretty good and really doesn’t affect the rest of the response keeping all other frequencies nice and flat with almost no attenuation

Good alternative
This is a handy little component if you're working with RF signals and want to make sure no DC voltage accidentally passes through. It's essentially a capacitor in a coaxial package with SMA connectors. You just screw it in line with your RF cables. What I like about it is its simplicity and effectiveness. It does exactly what it's supposed to do – block DC while letting the RF signal pass with minimal loss. It's small, easy to use, and feels pretty robust. For peace of mind when connecting different RF devices, it's a worthwhile investment. Just make sure it's rated for the frequency range you're working with.

2W N-MF RF DC-Block,DC to 6GHz is -3dB down at ~700kHz, but it is under $15 so....
I measured this on my cheapie Network Analyzer (AURSINC NanoVNA SAA-2N V2.2) after calibrating it, and the "2W N-MF RF DC-Block,DC to 6GHz" I just got today measures -3dB down at 723 kHz. It seems to be rather flat out from 1 MHz, so I am very pleased with it for the money (<$15). This is truly the Gold Age of Cheap, but good enough for the Hobbyist, Test Equipment.
