Spray stops working
Size: 5 Ounce (Pack of 2)
I’ve been buying this product for awhile and keep experiencing issues. It protects your skin well but is sometimes hard to spray and half the time the nozzle stops working while there is still product in the bottle.

Pricey but works
Size: 3 Fl Oz (Pack of 1), Style: SPF 100
It works well and is definitely worth it, but it's pretty small and pricey for what you get.
