Happy I bought these
I bought these after I read an article on how they could help lower my electric bill. I haven't received my next bill yet, so I don't know if that will happen. However, without expecting it, they have improved the audio on my office speakers. Prior to using these, I had interference and a variety of annoying clicks or chirps through my speakers and headphones. After installing these, those random noises are either gone or reduced to a point that they don't bother me. Unexpected, but happy event - worth the money just for that. Super easy connectivity, plug in and walk away.

Dangerous Scam That Cost Me $400 in Damages
Dangerous Scam That Cost Me $400 in DamagesI bought 8 of these “Kigley Energy Saving Boxes” thinking I’d reduce my electricity bill. Instead, they caused serious damage to my electrical system.After plugging them in, I started noticing:• Flickering lights throughout the house• Continuous clicking from my UPS units• Wall outlets overheating• Damaged surge protectors and outletsAt first, I didn’t suspect these devices. But once I disconnected them, everything returned to normal. I later opened one up — it’s just a cheap capacitor inside a plastic shell, nothing else. No real technology, no regulation, and absolutely no savings.Because of the instability they caused, I ended up spending around $400 on repairs, including replacing damaged outlets and surge protectors.This product is not only useless — it’s dangerous. It shouldn’t be allowed on Amazon. Do yourself a favor and avoid this scam. Unplug them immediately if you already bought them.

Power saver
I'll give it a different rating once my electricity bill comes in October for September. Right now it's not possible to rate. They arrived to my mailbox...something I was expecting delivered to the door. Packaging was super tightly wrapped which is a good thing.
