Review on Proportional Divider Drawing Artists Pixiss by Kelly Caballes

First off I can't believe I've been an artist my entire life and have never owned any of these four items. Color and tint have always seemed very natural to me and I've never had to doubt it, BUT I see where two elements (a color wheel and a tint guide) would add more precision to my work. The viewfinder was totally new to me, as was the proportional divider BUT I saw a YouTube video of an artist using them and thought I might as well try them out and play with them a bit. I always strive to learn something new. All the elements are well done, I just wish the proportional divider had some sort of guide, at least I wish it had holes marked with number increments so I know what percentage I was decreasing or increasing by (god that whole sentence was pretty confusing, but I can't think of a better way to put it, good luck with the translation). I gave the products 4 stars simply because there were absolutely no instructions for any of the items. I think they assume that as an artist you either already know or are smart enough to find out. Back to YouTube I guess. I wouldn't stop you from buying this set, just make sure you know how to use them all or you have the option to find them in the video app.
