I just receive it and after a first test, it seems to work well to control my Canon EOS 70D. Certainly, it's all plastic and thus very light; but it has an advantage when you already have the bag + tripod with the camera and several goals, I think you did not want to weigh you down even more (if not more room to carry the sandwich and drink that will timelapse well for several hours at night :)) So my first impressions are very good and for the rest, to be seen over time. = 4 stars (and later with longer trials and the product endures through time, I'll 5 Stars)
To Amazon: very correct delivery time and product well enough packed = 5 stars
