I Wanted to Like It
Style: SPF 50, Size: 1 count (Pack of 1)
I really wanted to like it because of the great reviews it gets with backpackers and generally with people that don't like "greasy hands syndrome" after applying sunscreen. But after using a stick I found that it's just not that good.
The good: small, lightweight container. Not greasy. Good protection, I was in the sun all day hiking multiple days straight and only put on sunscreen twice per day and I didn't have any burning... and I burn easily.
The bad:
Value: the $12.53 sunscreen container only lasted about 8 days. And that was just my arms, neck, and half my face since I wore a shirt and long pants and a wide brim hat every day when hiking. I would expect this amount of sunscreen to last a lot longer than that on such a limited area. I'm not a big person either.
Application, chafing: it's the opposite of greasy, almost chalky. You use the stick to apply to your skin in stripes, then you have to "blend it in" by rubbing with the backs of your hands so your palms don't get chalky. Since the stick is so dry this requires a fair amount of force and it chafes as you rub it around. When your skin a bit sandy it hurts.
Application, crumbling: on a chilly but sunny morning, about 45 F, I applied sunscreen and small chunks of the stick crumbled off. I watched precious chunks of the already overpriced sunscreen drop to the ground.
Residue: while it's not greasy, it's physical sunblock so it gives your skin the characteristic whitish sparkle. That's to be expected. But what I didn't foresee is it will rub off on anything your skin touches. My gear had white chalk-like marks (technically titania powder?) on my shirt collars, backpack straps, sunglasses, and a few other high-touch items.
Overall I think it's a neat idea. I'm not overly disappointed with my purchase. But for $12.50 I expect sunscreen to be easier to apply and for the container to last longer than about 8 days. I can't burn $50/month in the summer months when a single container of chemical sunscreen will do the job.
Pro tip: you can buy food-safe 3 oz TSA travel containers. Load one of those up with chemical sunscreen and you have something that beats this in every way except for the greasiness, which you can mitigate by picking a lower SPF sunscreen (the 30 SPF you wear is infinitely better than the 50 SPF you skip!).

Great Protection w/out the White Cast
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
We had been using the ThinkBaby mineral sunscreen for years. I wanted to look for a similar alternative but with less white cast. I actually bought this on a whim because it had the fastest shipping at the time (needed it for an outdoor event we were going to). We are now three purchases deep with this product. In my opinion, I think it gives the same amount of sun protection as before without the white cast. It rubs in great. Non-greasy. Initially, the lack of added fragrance was a little off-putting because we were so used to the typical coconut or citrus scents, but we all got used to it. Definitely on my list of subscription purchases now. I wish it was available in a larger size.

Smells good, covers well, it does leave a white sheen, I don’t need to reapply.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I use this just once on my face in the morning, apply makeup over it, and I haven’t burned yet! Been using it for two years now. Unfortunate thing is that my face is not tan at all because it doesn’t allow any rays. LOL So I my makeup has to match the rest of my body… I stay under an umbrella at the beach for about half of the time that I’m there. Otherwise I am out in the sun. And I do not reapply this. I am in the sun between the hours of 9 and 1 PM and I’m in and out of the shade and sun half of the time. Still no burning. Actually I don’t think I reapplied it at all once I got home from the beach and I was out at the pool regularly for another hour with no shade. So it seems to be pretty darn good! Some people say they don’t like the smell, but I specifically bought it because I love love love the coconut smell. My daughter says it smells like bananas but I don’t like the smell of bananas and I don’t think it smells like that.
It does definitely leave a white sheen. Hence my need for make up.

Great for Hawaii!
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I spent hours trying to find a sunscreen that was “reef safe” since I was going to be spending a lot of time near corals and this was the best one I found. It doesn’t have any of the 3 ‘O’ ingredients that are known to damage reefs. And the zinc is non nano as well.
Sunscreen goes on easily. One of the better mineral sunscreens I’ve tried, this one actually smooths out like lotion and feels hydrating. Only leaves a slight pinkish hue, but that is inevitable with mineral sunscreens (that’s literally how they work in reflecting the sun). I could feel it on even in the ocean so I get protected, but still reapplied almost every 2 hours. No burns!
I didn’t use it on my face but my partner did and it never stung his eyes nor caused any breakouts!
