the 2043 as good .
the botton problem just on 2215 ,some products the botton as short then before,so when the short on the 2215 top place the botton not enough firm.
about the size smaller problem ,just on 2215 too .because we add the ANTI LEAK WALL on 2215 ,the legs place as smaller about 1.0cm then SIZE CHART data.
the 2215 can't use same botton at the top and bottom place.
i think no body think over infact we use two different bottons in one products,because looks same.
now the problems be closed ,about 30-40 2215 pants as not good and be sold out.we have manage money return for most buyer.
i hope any one don't mind email to us if not pleased ours products quality .
Zhong from China!
