I have used there products for years, I have used them for alot of phones. Currently I use them for 2 different pagers, a knife case and for my 7520. Although the BB case I Have is not leather it is Ballistic PaK Cloth, They actually hold up a thousand times better, and the sleep function works great. The best part is the cases are very inexpensive, If I remember correctly the BB case was less than $25.00. Also they come in belt loop or a realy sturdy metal belt clip.
