This thing is unlikely to pull on a professional device, but the combination of good functionality, tiny size and low price make the device "top for the money." I like to use it as a tool that is always at hand. Small size is not always a plus. Due to the tiny area of \u200b\u200bthe base, it can be difficult to touch it against the wall strictly perpendicular. But it's strange to write it down as a disadvantage.
