“We used the HumanCharger four times during the flight from ZRH to DEN. Our recommendation is to use it every 2 hours for a max of 4 times. We also used it in Lech for two days before departing for the USA. We would say that the results are amazing - almost no Jet lag!! We have been working full speed from Monday morning and have been having very restful sleep.”

"I was a huge skeptic of whether this was legitimate in its claims or not but decided to try it out. I travel to Asia from the US monthly and suffer from terrible jet lag especially on return. I just returned 3 days ago from a 4 day trip and use the Humancharger according to the schedule on the app. Not only did I have almost no exhaustion over my 4 days in China I have had zero issues on return. It seems to encourage very heavy sleep in my case and even a solid 8 hours on the return flight. For frequent travelers like me this is as big as finding eternal youth. I plan to test it again next month but based on this trip am a huge advocate. The design is compact, small and most importantly discreet so I can literally wear it during a meeting if I have to without disturb. Highly, highly recommend this life changing piece of technology and worth every dollar if I don't have to suffer like I used to."

"It works great, travelled for work 3 hour difference, and didn't feel it it like I usually do, going west was always fine, but coming back east was always hard, getting back to waking up early, this made me feel like I was waking up at the same time, even though it was 3 hours earlier."

"Jet lag has been a big deal for me for many years now. I really enjoy traveling, even for business, but whenever I have to go to Europe it takes me like a week to get used to the local time zone. I have tried everything, from melatonin to strict diets and sleep and exercise schedules. It helps, but there isn't a silver bullet. So, after much research I decided to give this a go. I first used it last week on my flight from New York to London. I started using it in New York, a couple of days before my flight to London. I used the companion app that lets you know when to use it and it was really easy to hook it up with my TripIt profile, so you don’t need to re-enter your travel details again. I stopped using it 2 days after I landed in London as I was feeling fully recovered from Jet Lag, so I would say it has cut my average Jet Lag pretty significantly. Worth the money! Also, you actually don’t look like an alien when you have them on!"

"Worked for me. I used this on a trip to Australia shortly after I got it in September and it really helped me be productive both going and coming home. I travel internationally a lot and will not make another trip without this device! I do believe that a part of the value is the app that tells you WHEN you are supposed to be staying awake and when you are supposed to go to sleep based on your destination. I combine this with melatonin tablets to help me sleep at the right times and the combination is very effective. I won't say that it makes it "easy", but in the past when I went to the Far East, it would take a week before I'd be fully on local time. With this combination I adjusted in about three days."

"I tried HumanCharger on my recent trip to Japan. Jetlag has always been an Issue for me. I travel a lot, usually business trips and very frequently Long Haul Flights. It used to take me too long to adapt to the new timezone and I was struggling with meetings on the first few days. A colleague at work told me about HumanCharger, it worked for him so I bought one. It comes with a tool that tells you exactly when to ‘charge’ yourself based on your travel dates and time and the time zones you’re traveling from and to. Last time I travelled to Japan it took me 5 days to recover from jetlag, and this time I was feeling fresh and recovered in a couple of days. Is not a miracle device, you also need to sleep and eat on the right time, but all together, it works. I recommend it."

"I am a frequent trans-Atlantic traveler (6+ times per year) and have always really struggled with eastbound jetlag. I decided to try HumanCharger for the first time a couple of months ago and I couldn't be happier. The device has drastically cut down the number of days I need in order to recover. The device is slick, easy to use, and is a simple way to fight jetlag. The calculation tool is great too, it makes it very clear when to take a "dose" of light based on your flight information. Well done!"
