I just bought both the Olive Oil and Mango ones (mineral oil and my hair DO NOT get along, so the other two were off-limits). I've only used them as leave-ins and to SOTC thus far, but I LOVE them.
My hair practically eats them up, but I'm pretty porous. I can use a fair amount without feeling weighed down or producty.
Next up is trying them as rinse-outs/DTs. I'm very encouraged, given how much my hair loves them out of the shower.
