I bought the exact same one almost a year ago.
Quality wise its okay, its sturdy enough to hold cupcakes but tricky sometimes to adjust/level. Found that it got scratched right away.When I received it 2 tiers were already damaged they sent me replacements immediately.
Their customer service is terrible, there isn't a phone number to contact them which is really frustrating!
If you search the "Cupcakes" section in the forum you will find at least 2 threads about "Efavormart" and their service.
If you are a hobby baker and would like to buy it for you, its a good price. Whereas if you are planning to rent it out, I suggest you get a something heavier more expensive.
