yes, if you already have the equipment, and the software, then it's good value.
I was shocked at the price of painter, and immediately started looking what the open source options were, and there are several that seemed good, but Krita wins hands down.
Unfortunately for me, I had an incident with my previous graphics tablet, in that I accidentally pushed the pen off the table and didn't realise, and one of the dogs chewed it up.
It was a fairly crappy Trust one anyway, but the UGEE that I have replaced it with is only half a man, or something.
Won't work with pressure in the gimp, until maybe the gimp 3.0 and in Krita I have had a hard time getting it to not be glitchy.
Apparently works fine in Ps and Painter, although I have my doubts.
(I don't use those programs anymore since I decided to stop using pirated wares, and there's no way I can buy them, or even rent the adobe creative cloud. 70 euros a month is just so ludicrous for me. That's half my dog food bill right there.)

In the end I am using it without pressure sensitivity and not really painting anything.
I have been making vector drawings in Inkscape and theoretically I still paint in watercolours, although as I noted somewhere else, I am not working since steemit came along.

thanks for replying
