Terrible delivery system. Unable to use
Size: 5 Fl Oz (Pack of 2), Style: SPF 50
I know the product is good because the cream form works well. The spray product is terrible. With both sprayers, I could not get the spray to work. I am not an idiot and I know how the sprays should work, but they don't. A product is no good if you can't get it out to use. It is awful. I will NEVER buy this product again unless they change the delivery system. NEVER!

Great sunscreen!
Size: 5 Fl Oz (Pack of 2), Style: SPF 50
We love this sunscreen as our compromise between conventional toxic sunscreen and pure zinc that proves challenging to work with! A few bottles lasted us an entire week of vacation!
