Classic and useful.

I purchased to gift my son for his apartment. It is both attractive and useful. The weighted base makes it functional and balanced, and all for a very minimal price.

Budget friendly and useful!

Light weight affordable and still nice. Could be a little bit heavier at the base, I really like it so far. Seems pretty sturdy, definitely will need to check in to see the longevity of the product. Overall good budget buy.
