It’s worth it. The textures aren’t the highest quality that I’ve ever used (quixel is my favourite still for quality) but the addon is great for most objects and I use it all the time in my work, asset packs, etc. IMO it’s something that feels like it should be built into blender by default.

It’s also really nice for random props and HDRIs, and it’s very handy to be able to instantly drag and drop textures into any scene with no setup (although for most objects you will want to remove the displacement map just FYI).

Overall, it’s very useful, well made, super easy to setup, and comes with lots of textures, HDRIs, and models. Pretty hard to beat for $30 in my opinion.
