easy peasy. They just WORK!
I have been an electronics engineer for 48 years. I have seen some amazing changes! And these little beauties are so far ahead of anything I know. Very simple to use, work everytime. I am converting my battery operated devices to LiIon batteries, using these devices to charge them.
Very easy to connect and the two colour LEDs make monitoring easy. They also fit in tiny spaces.

Good looking retro knobs.
Real vintage look. I needed 5 of these to replace missing knobs on my valve (tube) tester.
Now it look a million dollars!.
They came with an allen key.
And they fit the 1/4" shafts perfectly.

Domnt stay in your ear! Too soft.
I bought these as they look like, and offer the same noise reduction as my (everlasting) Protec ear plugs.
I bought a bulk pack because I wear earplugs whenever there's a chance of hearing damage due to noise.
But they are worse than useless. They are far too soft to stay in your ear. When polled up to insert in your ear, they dont unroll easily so dont make a good seal.
Not sure how the manufacturers arrived at the noise reduction decibel rating...
