I set up Rebecca's Sideboard with her Sabbath and Hanukkah Sets and I am pleased to say that I was very impressed with them all.
My favorite is the Sabbath set! The Samovar is so accurate and made of metal, the top lid comes off to fit the Teapot perfectly for warming (just like real ones do), that's why people wonder if the Teapot is a bit small but it was made that way to fit on top of the Samovar (Rebecca shows you this below). The spigot (plastic) swings left and right. The glasses are real glass, the candlesticks are plastic and the teapot is ceramic.
I give it an A++ (mostly for the part that AG remembered to give us a Teapot and to make it fit on top of the Samovar so nicely!)
