Bests & Worsts Reviews from Amazon

I got this after reading the reviews and all I can say it really does work! I use it twice a day, once in the morning and once after lunch and it really helps tell my body to wake up. It sets my circadian rhythm back to normal despite being an air hostess. After every long haul flight, I still wake up at 8am in the morning latest, thanks to light therapy. Before, I don't feel tired even when it's past midnight but now it isn't a problem when my body naturally wakes up so early. I'm not sure about seasonal affective disorder but it's worth getting if you work in day/night shifts. Pros: - it works well for resetting my body clock - the light is very bright - doesn't have weird smells which is a common problem mentioned on some reviews for other products - it's small enough to carry for my trips - the adapter works on voltages for all countries Cons: - the timer only allows 15, 30 and 45 minutes intervals Get one if you have problems with controlling your body clock.
