The original video is clearly a review and he clearly criticizes the product for being hard to install even though he is of course installing it incorrectly and not using the materials the company provided. He states unequivocally it's a bad product here: "It's a bad product. It's bad because it makes absolutely no sense and nobody should buy it".

While not saying out right that it is bad, he is certainly implying it and clearly telling his audience that they should not buy it.

At 32:42 of the video of the original report.
