I'm excited. Of course you can also take a cheap egg timer and it tinker with something a smartphone holder. But here you have a beautiful product, an iPhone holder and to the opportunity to screw the whole thing on the tripod. So even at a Gorillapod or other terminals etc. The egg timer can then not. The iPhone-holder is standard, the iPhone 5 (of course without the protective cover!) Stops here not really strong enough. In inclined orientation I do not dare to use it. Here, I'll get me something else. The device is quite nice, feels good and the resulting time-lapse are pretty good for my fun-claim. If I were to answer it because professionally, I feel that the swing is not running exactly evenly. But hey, this thing is designed for mobile phones and a maximum ne GoPro, which has then eh not much to do with high-end, gell. So for the fun it gives me: 5 stars For the iPhone-holder: 3 stars For a professional result: Nix, who does not belong on this product!
