I bought this to use at a baby shower for displaying cupcakes because I'm philosophically opposed to buying kitchen items that do only one thing - so a dedicated cupcake tree was right out.
This set worked beautifully. Since the plate portions are not perfectly flat (as you can see in the picture), I used shredded paper basket fill to prevent the cupcakes from tilting inward. Filling the plates with M&Ms or jelly beans or other small loose candies would also perform the same function. A bonus was that, since the tiers are standalone, I didn't have to have them centered - I positioned each stand a little off-center on the one below it.
The result looked so good that people assumed I did this for a living - and it was just cupcakes decorated with colored sugar and cupcake picks.
I was a little concerned by another reviewer who said that the plate and the foot were cheaply glued together and that the glue was visible, but I think that might have been bad luck. My set looks great and all the pieces are clean where the plate and foot are joined.
I would absolutely recommend and purchase these again - in fact, at this price I'm thinking about getting another set.
Pros: Multi-functional, feels expensive because it's glass, looks great when serving.
Cons: The packaging is horrible - the box is divided into three triangles with a piece of bent cardboard and one tier goes into each triangle. No styrofoam, no paper, nothing at all to cushion the pieces - and the pieces don't fit that snugly into their sections. Mine arrived with no damage, and based on other reviews it looks like only a few people have had problems - but I'm really surprised that's the case. Still, at this price and value, I'd recommend taking the chance and purchasing this set - just purchase well before you need it, and make sure of the return policy, just in case something does happen.
Note: When I purchased these in 2009, they were $25 for the set - well worth the price. I'd consider anything under $30-$35 to be worth it, and anything under $25 a steal. For over $35, I'd probably look around a bit to see what else was out there.
