Looks expensive. Wheels could be better.
Model: Model B with Removable Tray
This got RAVE reviews when I wheeled it into a neighbor’s Thanksgiving celebration. The guests thought it was WAY more expensive than I paid. That said, the wheels aren’t all that great; the cart got stuck going into and out of the elevator. I had to lift the cart to get it over the track. But overall, I really like it. One caution. Read the instructions carefully so that the wine racks fit. I didn’t assemble it correctly, and it became apparent when the wine racks would not fit. But I was able to quickly disassemble the necessary sections, and reassemble them quickly.

Price vs quality
Model: Model B with Removable Tray
Aside from the fact that it's beautiful ,price wise is very competitive. We didn't want to occupy too much space in the living room so a bar cart seemed the best option. And this one caught our eye. Easy to assemble, very sturdy and did I say beautiful ??

Great addition to our home
Model: Model B with Removable Tray
Putting together took a little time but instructions included were easy for me to follow. Putting the screws in for the shelves required a little work to get then started but nothing that I would say would be a problem to do. It is very sturdy and looks great in our room we are transforming into a hangout/bar area. I can't wait to get all my accessories in to add to it and display all my nice bottles I have. Great cart for the price.
