Acycooly 1 We decided to buy online because of the wide-range of choice but what a disappointment. First there's size issue. For the same size in-store, this one came a bit taller for our child (this is supposed to be size 18 but feels like 20). Then LO always complains that his behind hurt, so the saddle is not really comfortable. And last but not the least, the piece that allows the saddle to be adjusted on the body don't look like the one in the picture in the manual so we had to make an extra purchase, because it was too small.The pro part I'd say is their customer service. What we asked for came quite fast and they were really polite. Too bad.
