These bands comes in really handy whenever I have to bring C out for outings to the gardens or farms. It really keeps the mosquitoes away and when I'm done using it, I can keep it in the aluminium ziplock pack and re-use it for the next outing. It can actually last longer than what's stated on the package. I don't use it often but it can be kept in the aluminium ziplock pack and even on the next ocassion when I use it for C, it's still very effective! Well that's usually weeks apart and the smell is still so strong. When I let C wears it, she doesn't get bitten at all but poor mummy gets all the bites ;) So yes it can last longer than 12 hours IMO.
I had enquiries about the Bugslock from other mummies. It's MADE IN KOREA as stated on the package not MADE IN CHINA! This is a product from Korea and naturally manufactured in Korea. If you receive one Made in China, well, think twice about using it. It might be an imitation. Bugslock packaging differs in different countries but they are all Made In Korea!
Let me see if I can post up the different packaging here....
There you go! The different packaging for different countries :) On the left, it is for sale in Korea, the middle packaging is for sale in Europe/US and on the right it is for sale in China. It should be stated on the back of the packaging that it is "MADE IN KOREA" not anywhere else. Hope the information is useful to you :)
