In this article, I would like to make a critical review on nozzle for grinding metal from the popular YouTube blogger - Mr SunY.

As an example, in the video blogger shows how to use this nozzle made by the hands, can be polished strip of metal.
Idea
Evaluation 4 of 5
Evaluating the idea of the present invention, I found it quite interesting, as often happens in life are moments when in the garage, must be sanded any small detail, but the grinding wheel not at hand, the present invention is in my opinion, could help in a similar situation.
The only negative is the large number of spent materials, in my opinion, they can be minimized.
For this idea to the author put 4 out of 5 points.
Design
Evaluation 2 of 5
Evaluating the design of the invention, a self-made, I am inclined to the view that it is contrary limits options Use of the present invention, a place in order to expand them, since this effect is time and is expected by innovation.
If we compare the present invention with a conventional nozzle in the form of felt circle for the screwdriver, such attachment can be sanded surfaces much larger than this homebrew twig. Since it has a metal frame of the bracket.
According to the invention will be very difficult to polish, or any heavy object, since it assumes that the object that must be sanded is served on top of this nozzle.
Since the present invention, on the contrary it reduces the area of application, the forced supply 2 points out of 5 for the design.

In this attachment, there is no clearly defined design is probably the author of the present invention did not set such a task. As you can see from the photos, the present invention as the same has not been dyed.
The color of the instrument with your hands would increase the pleasant perception in these tools users.
analogs
Rating 0 of 5
Analogues in this device very much and the price starts from 1000 rubles, probably buy a ready-made attachment will be much more effective and easier to collect than the present invention, with their hands on the author's instructions. Since these ideas quite a lot of analogues, which by comparison with the cost of materials used, and to buy them is not so difficult, was forced for this item is set to 0 points.
