Pros are that you can see the items easily that you have on display and the price is good. 
Cons are:
The shelves are not adjustable but you can leave some out if you need more room
You MUST display only light-weight items (total of 10 lbs per shelf) or you will pull the screws out of the shelf supports
This is difficult to put together because you have to insert the side glass pieces into a long plastic strip while keeping the bottom edge inserted into a groove in the bottom wooden shelf piece
You must clean the glass and plastic pieces as you go. If you don't, it is difficult to clean some areas once assembled because the wood shelf support strips block access to parts of the glass. I also found a tiny piece of styrofoam lodged in one of the plastic strips after I finished assembly so be careful of that as well. I elected to leave it since it's at the back of the unit and was so difficult to get together in the first place.
