Personally I think these lamps are my overall best product, lit or not they look great as the center piece of a table and the rich dark colors and dramatic grain of walnut are irresistible as a talking point with your guests.
Don’t worry about breaking the glass my phone number is on the label in a recess in the base and I always carry stock.
The mechanism is not subject to wear and tear the only thing that ever goes wrong is in over enthusiastic cleaning. I recommend holding the parts under a running hot tap to remove any wax buildup without any effort. I also prefer to let the copper dull down with age but if you prefer it to gleam I use solid copper water pipe stock, its never going to wear through like a plated surface finish.
