were ordered by me 2 Paral Raid Night & Day mosquitoes plug + 2 refills, further I each ordered a digital timer for both connectors.
In Spain holiday both male came by timer in 2 different sized bedrooms overnight use, and what can I say? -> The money you can save complete
Short to plug:
1. you can smell nothing
2. you hear nothing
Within 3 nights we counted a total of 22 mosquito bites spread over 3 persons (2 in a & 1 in another bedroom). I had may safely bought Nachfüller to the up to 30x 8h to comply with, which I did not reach far. Despite Nachfüller there was no improvement.
In short order, rem. Days has saved us the air conditioning, because it are these mosquitoes do not know God.
Conclusion: rather invest the money in ordinary mosquito nets, to give preference as Paral.
