Cubebrush is an interesting place for buyers and sellers, but very risky if you belong to the first group. I've come across users who sell products they don't own the rights to (they certainly didn't get permission from the real authors to redistribute them). I bought a couple of STL models from some seller, and only found out after that he was a scammer - in fact, the purchase can be considered as illegal, like downloading files from warez sites. This deducts a lot of points from the "credibility" of shopping on this platform and you have to be careful before buying.
I've been shopping on Cubebrush for the last 3-4 years for photo packs (primarily) I use as reference and Photoshop brushes and I've always had a great experience. Once there was something missing in a pack I ordered and the customer support rep got it sorted out with the seller directly within a day. Highly recommend for all sorts of awesome resources for artists.
I've had really good luck with this site. Marc is a wealth of knowledge and if you're patient he puts his courses on great deals. It's a bummer there've been some refund issues for some folks, but the weekly freebies and variety make this one of my favorite sites to browse.
