I've seen some negative comments did say you are limited to 399 photos, Which is not the case, you can set it to unlimited fashion (0) Which Means it'll take photos until your card is full. The timer performs great, excellent for timelapses and hyperlapses, ie for remote shooting. There's a decent amount of cord on the timer, Which is good if your camera is set up in a hard to reach or awkward place. Great value for money, highly recommended.
