1. All other crystal shells I've examined pictures of, I can clearly see 'clips' protruding in order to keep the handheld and shell together. This one, (http://lightake.com/detail.do/sku.Exquisit...ent_White-26062), I see no clips, so is it able to hold on to the handheld? So when opening the shell, will they open together? 2. Are those rubber anti-slip pads on the bottom? Others, (http://lightake.com/detail.do/sku.New_Crys...e_for_DSL-28150 ;http://lightake.com/detail.do/sku.Hard_Cry..._for_NDSL-23323), are just smooth plastic on the bottom, am I right?
