Lifeguard, 5 Count

I love this product! It monitors UVA & UVB rays and reminds know when you should reapply sunscreen and eventually when you've had enough sun for the day! My kids love the color changing factor and I love that the sunscreen goes ON THE BAND every time you reapply so you really have an accurate reading. The other cool thing is that its waterproof so they can wear it in the water at the beach or pool. Great for camp too :)

The bands came off very easily as the children played outside in the heat.

I used these to help monitor my fair-skinned daughter's sun exposure on a recent cruise. The whole idea is that you expose the bracelet to sunlight to activate it, place it on your child's wrist, and cover it with the same sunscreen you're using on your child. As the effectiveness of the sunscreen begins to wear away, the color of the band changes letting you know that it is time for another application, or to get out of the sun altogether.The bracelet worked well for the initial application, but I was much less certain that the bracelet was an accurate indicator of exposure after the second round of sunscreen. It didn't seem reliable after that. For the rest of our trip I ended up not using the bracelets and just timing the sunscreen applications to be on the safe side.

Worked as promised , one use only, the tabs were a bit to easily caught and pulled open, and once the bracelet was opened, not able to reapply (of course). The sticky part needs to be closer to the end. Would help too, with those of us with big wrists (read: not kids/tiny adults)

good price, fast delivery.
