Review (4/5): good overall sun protection
There is always a debate on what SPF to use. 30 is a good choice, as that is 30 times the protection, versus no protection. This means the product would give 30 hours of protection vs. 1 hour of no protection. 30 minutes vs. 15 hours or say if you burned in 15 mins, this would offer 7.5 hours of protection. Product goes on smooth, I can feel a hint of residue which I do with any sunblock hence the 4 star. . It has a slight smell similar to the name brands. All around great product.
