Heater

Bought the heater at 9kW. This is perfect as it keeps it hot and works well. The manuals made it pretty easy to set it up all ourselves and get it going.

The colors are nice

I bought a chandelier from the home upgrade, the colors of it are nice, but i also was expecting for it to come in with replacement parts for the handle in different parts, so if I dont like the first color, we can switch it up. Unfortunately it didn't come with other parts on the side
