I love that the primer is cruelty free, mineral and 83% organic, and that it contains HA and other hydrating ingredients. It goes on nicely, feels good on the skin and is hydrating. I didn't love the smell - I don't really like herby, botanical smells in face products. I did find it provided a nice base for makeup and gave a nicer, smooth finish to my makeup - especially around the eyes and mouth where fine lines can happen, it was lovely and hydrating. I didn't feel that it helped my makeup stay on all that much longer though unfortunately, than it would have with a nice moisturiser. I will stick with my current primer.
I think for people who will only use vegan and/or mineral products it could be worth a try.
