This is a nifty addition to the studio. It does require a little patience to operate, as it is a bit hard to turn the face of the tool to size the circle to the smallest setting. The tool gets stuck at 1 1/2 cm mark and I have to use the screws on the back of the device to move it down to 1 cm. The larger the circle gets, the easier the tool turns. Beware of the edges of the inside of the circle, they are sharp and will damage your drawing utensil if rubbed against. This tool takes the time of making perfect circles by hand away so you can focus more on the overall work instead of minor details. I can also use this as a “curve gauge” to help get the same line curves in some of my more abstract art or different line curves in proportion for designing. Nice quality and heavy-duty product.
