Having a spray sunscreen is great due to it being convenient and easy to apply. Although it dries relatively quick it does feel a little sticky on your skin.
As a dark skinned person I do like that it does not leave a weird residue on your skin, guess its because its a spray. I would say it somewhat protected my skin as I did not burn.
For use wise I don't find spray especially helpful as I'd only use it for hard to reach places... But would still need to rub in to make sure I didn't miss a spot. Plus not as much comes in the spray and what does gets used / blown away in wind way too fast. I'd prefer to use lotion as it's more cost effective and easier not to miss a spot
