So, there are two bottles of suncream, identical in every way other than the type of dispenser. Same manufacturer, same brand name, same ?type?, same SPF? I usually buy the spray bottle but they keep getting blocked ?and I keep missing DS and spraying the wall?so this time I pick up the bog-standard bottle. At home, I notice that the UVA rating for the bottle is 3 stars. Hmm. I double-check my spray bottle and the UVA rating is 5 stars. 
Not the most important issue in the world but fairly irritating. AIBU to have expected the two bottles of suncream to have the same UVA rating?
