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.

Great product
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Product is great with good coverage and ease of use. Much better than comparable products because it is very light feeling and doesn't leave a heavy or sticky residue on your skin. Perfect protection for anyone who burns easily or fair skinned. However I paid for the extra rushed 3 day shipping and it was delayed and I wasn't reimbursed the extra shipping charges even though it arrived 6 days later.

Save your money- don’t buy
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Purchased this for our trip to Mexico. At two cruise ports we were doing a combination snorkel and pool day. I got this sunscreen because it was reef friendly and came with two bottles. Both bottles were IMPOSSIBLE to spray. You could not sunscreen yourself because you had to hold the bottle just right, push down with extreme force, and have your fingers place very specifically on the lid. My 13 year old and husband couldn’t even use the bottles. I did figure it out so I had to continually sunscreen everyone in the family. No one in my family has sensitive skin, but we all ended up with a fine rash after using this sunscreen. On days prior we used another brand and no one had a problem. We also reapplied often (every 60-90 min) and we still got pretty burnt. Maybe we got a bad batch…

Great sunscreen that smells good too!
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
This stuff actually smells good and the scent doesn't smell like chemicals. It comes out clear which is perfect because I bought it for my little blonde headed, fair skinned 16 month old. It's nice to not have his hair looking all weird with white sunscreen spray. Overall, very pleased with it! Came just in time for our trip to the zoo the other day!
