I actually just one bag and a spare battery for my new Canon IXUS 170 wanted and then I stumbled across this interesting trio. Bag is well padded inside and has additional storage space for the spare battery and the spare memory card. You can reassign the case also (strap is), but I prefer rather to the belt. The battery Lookit NB11L does not differ from the performance so far from the original. About longevity I can write anything, for that I have him not long enough. Description of the goods is exactly the same delivery. Along with the 8 GB memory card is a good trio at a fair price.
