I purchased the spray (with SPF 20) last year on holiday for the first time as Notkauf. Because to me, but actually is too low for the summer, I have now again ordered the 30s in the action. (In recent years, I used because of allergy (see below) are often much more expensive Ladival.)
To smell: I find that the spray smells very good, I've had better, but it is not a substitute for his perfume ;-)
For sun protection factor: Even at 20 I could not say that we were burnt despite sunlamps. However, one has to be regularly Reapply. Therefore, now the '30s, ...
For Spray: The Spray attracts actually a fast and leaves no visible traces. I see here, however, no difference for comparable product from a large discount (AL South), which I have tested even at friends. In addition, my experience is that you rarely really so "is sprayed" but sprayed into their own hands and then distributed (especially when one is not only in swimsuit on the beach) is. Because it's quite a bit next to it and if necessary to the clothes. Thus it loses this advantage over a cream.
Price: I would classify the spray priced in the upper midfield. But of course there is much more expensive.
Allergy: Although is not explicitly advertised as other products I've been able to detect any allergic reaction in this spray. However, the sample is too small for a definitive conclusion.
Overall, I am not dissatisfied with the spray, but also see potential for improvement. Since the regular price is relatively high, a good three star.
