I just bought this SL910A and it is great. the connection was very simple. the menu is user friendly and simple management of contacts. the answering machine is full and simple. Menus are clear. sound quality is perfect and the screen is large. I was surprised the black box but as it is bluetooth can be left near the l-box and put the phone and small or medium you want.
my friends are surprised when they see the phone and find it awesome.
Small - ringtones are not great, I'll see if I bit download. the phone is a little heavier than I thought
