⭐⭐⭐⭐ Pretty clever and handy.
By R. Wessner
⭐⭐⭐⭐⭐ So Clever! Easy instructions
By Brandi F
It lit right up the first time we used it, we had no problems at all and it lasted a long time! The light is just perfect, not too bright, but bright enough you can see. The light would be great during power outages...no need to worry about batteries. My husband just couldn't believe it worked so well off of water only!
⭐⭐⭐⭐⭐ I cannot say enough great things about this flashlight!
By Lauren C
This thing is amazing. You literally only have to dip it in water and shake it off a little and put the cell back into the base and IT REALLY WORKS!!! I did it for the first time and left it on for an hour, then I turned it on every day for 5 days in a row just to see if it would work and it did! When it runs out of juice you just wet it again! This is going to be an amazing product for my daughter when she goes to summer camp this year. Also great for power outages. No need to worry about running out of batteries! I love that you can alternate between flashlight and lantern mode depending on what you're using it for!
⭐⭐⭐⭐⭐ Think it can't be that easy? Yes it can!
By Tricia
The husband and I already decided the dads are getting these for Father's Day but we aren't going to tell them how to use it. We'll let them be as amazed as we were when we read the instructions.
⭐⭐⭐⭐⭐ I bought the Hydralight a few days ago and couldn't wait to try it out!
By Anton B
Wow, this is truly awesome! Love the rugged built, have bought a few and placed them in the car, around the house, in the garage, etc., great for emergencies!
⭐⭐⭐⭐⭐ The Hydralight has been pretty impressive.
By Photolady
The instructions were very easy to follow and I was amazed at the ease of use. This light would be great for camping or any outdoor activities.
⭐⭐⭐ I was more curious than anything else.
By Mike
It really works, not to bright but handy if nothing else is available. Add water and it works again. Very cool.
⭐⭐⭐⭐ You had me at no batteries needed!
By Star Wars Fan
⭐⭐⭐⭐ This light is pretty great! It is sturdily built and good quality.
By Elizabeth S
⭐⭐⭐⭐⭐ This is the coolest thing I've bought in quite some time.
By B Strickland
I had my doubts as to whether it would do what it said it would, but it works! We are planning to take it camping with us when the weather warms up.
⭐⭐⭐⭐⭐ This thing worked better than I had expected.
By R Burgees
Soak that little battery for a few seconds and get a nice long charge. This has come in handy a couple times during recent power outages. It is not super bright but plenty bright for normal use.
⭐⭐⭐⭐ This flashlight works just like they advertise, both as a flashlight and as a lantern.
By Rose W
It feels heavy duty both by weight and by materials. It is amazing to see it work so well by simply soaking the fuel cell in water for a few seconds, shaking out the excess water and inserting it into the light. One charge lasts for days. Mostly, we've been playing with it on and off to see what it's capable of before we take it somewhere we have to rely on it. So far, so good!
⭐⭐⭐⭐ This will come in handy in a pinch.
By K Henninger
Works great when you follow the directions and it lasted about 8-10hrs. Not as bright as an LED flashlight obviously, but still a great purchase where I don't have to buy batteries! I like that you can make it a lantern as well! I would buy again and I would recommend.
⭐⭐⭐⭐⭐ This is awesome thing to have around living in south Florida during hurricane season.
By Krav
The light runs on water so no need to make sure we have batteries. We will be buying a couple more so we can light the house if the power goes out.
⭐⭐⭐⭐⭐ Great idea for a flashlight, this actually just came in handy by a recent snow storm that knocked out power to our home for a few hours.
By RaffM
Just dipped it in water and it provided us with really bright light and it didn't dim at all the entire time it was on.
⭐⭐⭐⭐⭐ I'm in love with this item!
By Pinecone505
I followed the instructions and charged the battery in water and instantly the flashlight worked! I left it running all night in our hallway just to see how long it would last. It burned the same in the morning as it did when I went to bed. I feel better knowing that I have a flashlight that will work when the power goes out and even if I run out of batteries! Great for emergencies, this item will be going to camp with my daughter this summer!
⭐⭐⭐⭐⭐ By KP
This past winter, the northeast was bombarded with snowstorms. When the power went out, the Hydralight was easy to get going so that we could see. It is a great functional light.
⭐⭐⭐⭐⭐ Is this amazing or what!
By Vicki 5
This will make some nice gifts this coming birthday and Christmas season.
⭐⭐⭐⭐⭐ Charges fast with any kind of water!
By Miss TG
⭐⭐⭐⭐⭐ I really enjoyed this flashlight.
By M Renee
It is very bright and lasts for a long time. I love that all you need is water to make it work as regular batteries need to be replaced and sometimes you don't have new ones on hand.
⭐⭐⭐⭐⭐ I pulled out the little fuel cell and soaked it for about 20 seconds, shook the extra water out and wa laa!
By Shawn O
It came to life! I thought I was being scammed but this thing actually works! Hopefully I won't need it because it looks like the hurricane is going to miss us but it will be nice to have just in case. Well worth it!
⭐⭐⭐⭐⭐ A must have for any household!
By CraftyNicoleH
In eastern PA we get a lot of blizzards and weather events in the fall and winter that knock the power out. Having batteries on hand doesn't always help as sometimes we lose power for a week or more. The Hydralight is truly amazing and works exactly as described.
⭐⭐⭐⭐ By Kate
I live in an area where we always have to be prepared to be without power due to hurricanes, severe wind and lighting storms and poor electrical infrastructure. We have an emergency kit that is always ready for action. Lighting is always one of the biggest challenges. I love the fact that this flashlight and lantern is so simple to work and provides many hours of light. The lantern feature is my favorite.
⭐⭐⭐⭐⭐ Absofrigginlutely impressed by this!!!
By K McKinney
Works just as posted and I love that I do not have to find clunky batteries and add to the landfill. This is a fabulous design concept and will keep it in mind for gifts in the future!
⭐⭐⭐ By Lanbro19
It really does work on water, just not too bright. Will be good in an emergency.
⭐⭐⭐⭐⭐ This flashlight is AMAZING!
By Mom of three
I do not understand how it works! It's easy to just dip the cell in water, shake it off and you have light. We plan on using this for camping and no longer having to worry about always having batteries!
⭐⭐⭐⭐⭐ This thing is seriously sturdy.
By Katie
And I love the fact it is a flashlight and a lantern! The novelty of it being water activated was super cool for my son!
⭐⭐⭐⭐ By E Idaho
What a cool flashlight!!
⭐⭐⭐⭐⭐ By V Gledden 5
After living with no electricity for over a week last hurricane season, I have been looking into alternative lighting options. The Hydralight meets this goal! It was easy to set up by dipping the “battery” in water, shaking, and inserting in to the flashlight. The flashlight itself is sturdy feeling and the brightness is comparable to other flashlights I have used. Using it as a lantern is a nice option as well. I kept it turned on for 7 hours the first day and 8 hours the second day to test out how long a charge would last. I was amazed at the fact it was still lit after that time! I have only had it for a short time, so I am looking forward to seeing how it holds up over the next hurricane season.
⭐⭐⭐⭐⭐ By M Ehrhart
Great product, it's so cool how it works not having to use a single battery. The flashlight shines very bright at what you're looking at and the convenience to just pull the top up and it turns it into a lantern for hands free operation.
⭐⭐⭐⭐⭐ No batteries just a fuel cell to power the light. Dip it into water and bam light on.
