Query: Great Space Saver; shoddy design

I love the vertical and two-tier design because it helps to save counter space. What I don't like is the quality of the design - the pegs keep falling off. The drain is not very effective unless your counter-top is also sloped. The rack also needs to have more center weight to accommodate heavy glass bottles - it sometimes topples over when I don't evenly distribute bottles on the rack.
