Leviton LB120-DS 20A 1-Pole Plug-On Smart AFCI/GFCI Branch Circuit Breaker, Hydraulic Magnetic, 120 VAC, White

Just what i expected

Quality materials. If you use the App to monitor energy usage, set alerts on smart breakers for when a fridge circuit doesnt run as an example, or trip breakers - prepare yourself for a very poor experience. It appears they had an issue in December of 2022 that resulted in the usage data just not being there/lost. Opened up a support, after two months I got a response that they would fix it with a future app update. Three app updates later they did, by removing all of 2022 data and only showing 2023 calendar year. But it only works on 15% of my breakers, the others show 0 data. If you are looking for a good quality non-smart breaker, this is a very expensive paper weight basically. If you want some smartness to it with support backing their product - this is not what you should buy, go elsewhere.

This serie of Smart breaker makes a buzzing sound when connected to power which is all the time. While one doesnt make much noise by itself, you can hear 30 of them through the door. Thats a real problem for a product so expensive and its simply unacceptable. Ive contacted their support and apparently this is by design. Screw this. Im not building another panel with these... Im committed now but I wont do the same mistake twice.
