but this does sting like crazy if you sweat a lot
I did not get sunburned, but this does sting like crazy if you sweat a lot, which I do.  So if you aren't sweaty, buy it.  If you are, be prepared for it to hurt, but still prevent your sunburn.  I visited two very sunny locations and did not get burned at all!  Well done, Neutrogena.
