Well, the only trap this offered was when we threw down $30 for their device. After downloading the app to our iPhone we were ready for the first test. A simple one to start with, we did a 5 frame bracket. After following a very easy interface we pushed the TriggerTrap app button, then waited and watched. Well, it did actually work, but as far as what it did, that is when the disappointment set in. We got 5 exposures one time, we got 3 another, we even got 15 with the same settings. We got different results every time. So, we only wasted $30 to do a quick review. To sum it up, if anyone is interested in owning one, drop us a line we’ll give you ours.
