States power glider i took glder as rocker when the delivered it was not set up properly I asked the about the flap in the back the said sorry it just hangs lime tha noticed velcro and the flap was not long enough so I noticed the back was installed wrong. Re installed back flap and velcro sealed now.  It was frustrating  because I went through a broken part reorder I won't order lard stuff from qayfair again
