I also have a Logitech Presenter R800 for comparison, which can come up with some plus points over the Inateck model.
The Logitech Presenter is slightly longer and more difficult, it is better in the hand. The thumb is now the right postion for indexing of images, while you have to bend the thumb more when Inateck model to achieve the shift keys. For users with smaller hands that might not be a shortcoming.
The surface of the Logitech model feels more comfortable, the rubber is grippy. The surface of the Inateck model is smoother and cheaper.
In my Inateck model one sees immediately negligence in the processing: the display below the window is moved and is not fit under the window. This will not be a series error, but in my model it is unfortunately like that. The radio receiver can be the Logitech R800 (and similar design versions) lighter from his storage pit pull than when Inateck model.
However, points can Inateck model in the equipment: The side buttons for volume control when the sound you miss the Logitech model, the timer function is easier to use. On the lower side rocker switch, which activates the red laser beam, however, I could well do without, because you get sometimes unintentionally against it and triggers it off. The asterisk button on the top is sufficient for this function.
