Really well designed and thought out article. I was on a small budget and did a lot of homework before deciding on this item. I bought this to work with my weebils and had really high hopes that together they would give me a very decent motion control option for my camera without spending a few thousand dollars. The first one I got had the drive motor not starting after the suggested upgrade so unfortunately I sent it back and bought it from Revain thinking I'd just gotten a lemon. It showed up with a missing charger which of course I needed so I replaced it. Which turned out to be a completely different slider from the same manufacturer, so I swapped it out again. The fourth showed up with all of its parts I'd put together with Weebil, and while it took me a while to figure it out (drive points in an app work backwards how you program them), I had it working as a programmable 4-point -5-axis motion controller. I was very excited. The next day, after setting up some scenes to perform this amazing combo, at that precise moment the app asked me to update, which I did. After trying this update, the engine on this second unit did not start like it did on the first. What a pity. I want to believe that with all the effort and great design work that went into this device, they will eventually fix the bugs. Although that time is not now. I really wanted this to work as there is nothing on the market that even comes close to what was promised in it. Maybe you can do it, or maybe you can fix it. Another example of not quite ready for the market. I might try them again in a year or two. If they are ultimately able to deliver what they are promised, this could be an amazing item at an unbeatable price.
