Siemens Q23040CT2 30-Amp Pole/40-Amp Double Pole 10-Kaic Circuit BreakerSiemens quadplex type QT breakers are a 1 2 Inch frame per pole and are suitable for use in Siemens panels that allow CTL type QT breakers.

The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.

Size: USB C to Ethernet Adapter

For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer. I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.

Worth every penny

Size: USB C to Ethernet Adapter

This adapter provides a stable, hardwired connection when Wi-Fi is not fast enough for heavy law school research. It is strictly plug and play, requiring no software installation. The weight is negligible, making it easy to keep in my bag for campus. Given the excellent build quality and consistent functionality without any drop-offs, it offers solid value for money. It’s perfectly versatile for numerous uses (keeps me from having to use like 3 other dongles)
