I bought this for my summer spent in Ukraine so I would not get sick from their water. It worked for me, I was fine the whole time and never got sick. I dropped the water bottle once pretty hard and it starting leaking a bit from the top after that, but as long as it was upright and sealed tight it worked. Water tastes good too.

I installed this myself and had zero problems. They send the plumbers tape and I had a pipe wrench to tighten it with and have had zero leaking issues and it works beautifully. I would definitely recommend this to anyone looking for an amazing water filter system. BTW I an a 52 year old woman, and if I can install this by myself anyone can do it!

It seriously doesn't leak! It's incredible!

And!!! It's easy for my 4 year old to open. :)

It works great and months later no leaks, or no cracks, I plan on ordering more in the near future.

Perfect replacement for my bite valve and doesn't leak at all

Works wonderfully! And, it's not one of those UFO-types that has a disproportionately large stopper top. Lastly, for those of you having problems with leaking, there is a trick that nobody in any DIY video I've seen tells you - you MUST use teflon pipe thread tape (3 or 4 rounds) on the large bottom nut, otherwise water WILL leak thru the threads.

The connections on this thing are absolutely great.  I have never had one of these that is so easy to fill, and disconnect and leave full without it leaking all over anything.

I had bought a camelbak based on good reviews, but the nozzle leaked intermittently.  This bottle I love.  I doesn't leak and it's well made.

It worked better than I expected. I even left it overnight with half a can of refrigerant in it and it did not leak.

My Suzuki Forenza had a small leak after engine shutdown and thought I should give it a shot as the car was 12 years old and didn't feel like replacing anything. So I crushed a tablet and put it in the coolant reservoir, drove the car for half an hour to work and later that day back and checked for leaks at home and to my surprise I couldn't see any leakage anymore. Checked again the next days and no leakage. For the price, this is definitely worth the try. it did the job for me, so very pleased and will use it again when needed.

I loved this mask it worked great. It was nice not to be bothered with two separate pieces. There was no leaking and it was comfortable.

After my sisters kept breaking my other sink stoppers which had strainers built in, I bought this one in desperation! It works great and does not allow any water to escape. It is easy to clean and wipe off. It is idiot proof and absolutely does not need anyone to explain how to use it or worry about it breaking any time soon!

I do use a strainer (bc we do not have a food garbage disposal) as soon as I unplug it to catch food particles, and thus far, it has worked fine.

I bought this flask last week and have used it on a long run.  I didn't experience any leaking like some other reviews have mentioned.  I think that the dispenser is innovative...you squeeze the bottle and it opens up like a nipple.  Before buying it, I thought that there might have been a removable top.  It remains ti be seen whether I have issues after prolonged use, but the first 12 miles were great.

It works really great! It does lock on and doesn't leak... unless it is a tight spot and you can't get it on squarely.  But it is well worth the money for the ease of use and cleanliness of the job.
