Pro - It looks nice and seems sturdy enough. If you are using it for a cart and not a microwave stand it will be easy to use and wheel around.
Con - It took 3 hours to put it together and the instructions were ok but not up to what we would expect from IKEA. 
Con - I am concerned because my microwave is 42 pounds and the cart is now a tip over hazard. I am taking the wheels off and putting rubber feet on the cart. If it still seems unsteady I will get rid of it.
