I have a IXUS 155. description of the product stopped at the Ixus 100 ... Well I can tell you that fits like a glove (almost in the literal sense) to the Ixus 155! Very beautiful workmanship, the case and the unit together form a gem ....! (That can even wear elegant saltire). As for the delivery ... let's talk! Ordered Friday 16h and delivered ... ... yes men on Saturday morning at 9:30! Crazy, right?
