### ⭐⭐⭐⭐⭐ Very impressive for the price
*by C***E on October 29, 2020*

I use this set for elements of iconography paintings. I am very impressed with the quality and accuracy for the price. In my opinion this set is well worth the price. I asked my husband, who is an engineer, what his opinion was of this set and he agreed with my assessment.

### ⭐⭐⭐⭐⭐ Works Well
*by J***R on June 29, 2021*

The device does what I need it to do. I was able to use my own pen by using the attachment that it came with. No need to buy the special ink that they recommend. However, I might look into it in the future.

### ⭐ What am I missing that the other reviewers seem not to mind?
*by D***O on July 27, 2022*

The smaller compass works fine, but the larger one is useless- the hinged legs do not stay put, and flop all over either throwing off your center pin alignment or drawing all over the paper. I think the company added the hinged legs because they look cool, but forgot to include any way of tensioning them so you don't mess up your drawing. Useless, do not buy!
