I don't know if it's the batch's fault, but I'm the only one who can smell the fragrance. I sprayed at least 20 times for the scent to reach the person across from me with the help of the wind. I don't know if this has happened to others; I will probably try to get the genuine one (Wavechild) and not a clone. 40 euros wasted...
Update: I'm back to report that the product failed to pass the authenticity certification of the parent company. I have sent the results by email and am awaiting a response...

It is a very nice summer fragrance with a strong watermelon scent. I recommend it mainly for teenagers as it is a sweet fragrance. With 6-8 sprays the scent definitely lasts 6-8 hours (at first it lasts less). For its price it is perfect. I highly recommend it!

I received and tried Atlantis! To be honest, I was curious about how the watermelon note would smell! The truth is that right from the start you can sense the watermelon (it really reminds me of some chewing gums with that flavor – and I mean that in a good way). The fragrance is relatively sweet without being overwhelming. It has very good longevity and sillage (6-7+ hours) and I smell it on myself several times throughout the day, which I like. It is summery, pleasant, and suitable for work environments since it is not suffocating. I recommend it without hesitation!

With watermelon as the main note and other fruits in the notes, Atlantis is an ideal summer fragrance. Excellent clone of Wavechild. Very good projection and longevity.
