Good quality wine cart.
Very sturdy bar cart and well made. Product came well packaged, with good instructions and even some extra screws. It is helpful to have 2 people putting it together. The only downside is the wine rack will not hold fatter bottles of wine but I added a small wine rack to the top.

Pleasantly surprised!
The cart is super-sturdy, easy to assemble, and looks surprisingly nice. You would think that the “wood” (the rustic oak) on this cart would look hideous, but it’s not - and it looks good with the black metal. Just make sure you have your own tools, like a screw driver with a 4 mm hex bit or an impact driver or screw driver with a 4 mm hex bit; it would take way too long with the supplied hex wrench, which although a good quality, is just too slow to use.)
