This was my first ever time-lapse product and thus far it has done a great job. I use it in conjunction with a Manfrotto tripod system and a Sony RX100 IV camera or occasionally with my Nikon D750. I've used it almost entirely for time-lapse work rather than the video panning feature. I'll break down my experience into pros and cons.PROs:1. Smartphone Interface: This works extremely well and consistently in my experience using an iPhone 6s. The setup is simple, the connection instant, and the interface makes a lot of sense. Via the app, you choose the duration of shooting, the duration of the footage, the FPS, and the angle of movement, all of which can be done very quickly. The ability to preview the footage in real time is awesome. I have not experienced any of the interface issues that others have mentioned. It is worth mentioning that you connect to the device via the Syrp app rather than via the bluetooth panel in your phone's settings, where it is not visible.2. The fact that the system is "all-in-one" is nice - you don't need both a panning device and a separate intervalometer.3. Size: The device is very small and fits quite easily in any camera bag, though you'll need a tripod, or at least a tripod head, to really take advantage of the unit's full abilities.4. Build: It's an excellently constructed device from everything I can tell. The rubber feel is soft and pleasing, the buttons are tactile, and the addition of things like the cork padding on top adds a high end, thought-out feel.5. Video quality: The end product time lapses have felt smooth and consistent. It does its job well.CONs:1. Expensive: This is the only major con in my book. You could build a system that delivers virtually identical end products for half the cost or less. What you're paying for with the Syrp Genie Mini is convenience. Unless you do a lot of time lapses or have the extra buckage to spend on fancy gear, you might consider buying a separate intervalometer and panning device.2. Could possibly do more: For the high price, it'd be cool to be able to change camera settings via the app as well, or even (though the tech isn't quite there yet) preview the image on your smartphone. Using wifi or a more advanced cable system might allow these features. Of course, could it do these things it would probably cost much more than it already does. Also, to unlock this thing's full potential you'll need a ball head mount on top. Note that using it atop a tripod head that is tilted up or down will give you funky movements (as with any panning head). If you want the camera pointed up or down at any angle, the tripod mount needs to be screwed on to the TOP of the Syrp unit, with the camera attached to the head (see my pictures to see what I mean).Overall, the Syrup Genie Mini is superb, though expensive. If you love time lapses and want to add simplicity and motion to the process, look no further. Thanks for reading.
