spray nozzle needs work.
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I purchased 3 of these cans. Only one of them worked and that one was ok. Sprayed well, smelled good and and protected my skin and even though it was hard to press it to work, we WERE able to use it, but the other three .............? They would not rotate to the unlock position, therefore they would not spray. My husband and I tried everything to get it to rotate. It seems both the top and bottom ring spin around effectively doing nothing. So to pay almost $40 for only one can to work is definitley not worth the money. Buy somewhere else.

Great product! Highly recommend! Worth the money
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Our family absolutely loves Alba sunscreen! It’s light, not super greasy, and smells really good. Everytime I see it on sale, I buy more of it! My husband is a red head, and he has to wear sunscreen all the time, and he prefers Alba brand over any others. Great Product!

Like the sunscree - not the spray can
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Sunscreen itself did a great job with our snorkeling and scuba diving. Long lasting and didn't rub off in spots where masks and other things can leave spots unprotected. However, the spray can itself was difficult. Even when being sure it was completely in the unlocked position, it would take me two thumbs at full pressure to get it started spraying at times. Definitely, only a couple of us in the party were the appliers as we could get it started.

Love it! Eco-friendly and Easy-to-Use Spray
Style: SPF 50, Size: 6 Fl Oz (Pack of 2), Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I really like the Alba Botanicals Coconut Clear Spray! Not only does it give me a refreshing coconutty vibe, but it’s also biodegradable and cruelty-free, which is important to me. 🐰♻️
The spray-on application is a breeze, and I love how it doesn’t leave that annoying greasy feeling on my skin. It absorbs quickly and leaves my skin feeling soft and nourished. Perfect for those sunny beach days or any time I need a quick spritz of hydration.
I highly recommend this coconut clear spray to everyone who values eco-friendly choices and easy-to-use skincare products.

Great product, bad packaging
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I love this sunscreen! I use it on myself and my child and it works very well. However, the spray nozzle on one of the cans is locked and it will not work. I have tried to turn the lock, lift it up, etc., to no avail. This item is also not returnable. $20 for 1 can of sunscreen is quite expensive.
