Doesn’t spray!
Size: 5 Fl Oz (Pack of 2), Style: SPF 30
So there is a barely visible lock/ unlock icon on the plastic strip under the spray nozzle. Turn the nozzle to unlock, and it should have sprayed. NOPE! I had to put the can on my bathroom counter and press as hard as I could to get the spray to come out and into my other hand. I then applied the lotion. It’s ridiculous how hard this is to use! So I can’t comment on the sunblock itself because it’s next to impossible to use it as a spray. Cannot recommend this product until manufacturer fixes the faulty nozzle.

Great sunscreen!
Size: 6.7 Fl Oz (Pack of 1)
We have used this sunscreen lotion on multiple beach vacations, and most recently on our cruise. The quality, coverage and protection are great. The lotion glides on smoothly and is not sticky. It has a light fresh scent that did not irritate the members of the family with sensitive skin. This is one of our favorite lotions to use, and we keep repurchasing it. The price point is great as well.
