Does it develop leaks over time? I use a cold pack for my lower back while sitting in a chair. This seem to be tough on these sorts of things.

We have only had it a month so no leaks so far. My wife uses it almost every day.

I have it for about a 4 years and no leak so ever. It's very durable and well made. I use it in the chair, too, in the bed - no problems.

I have been using it when sitting on the couch, when I am in the car and when I am out and about. So far no leaks. It lasts about 3 hours and is easy to carry in a large purse.

a year ago I had double knee replacement and used it nearly every day for months.... I do still use on occasion , but not as much now never had a problem and the shape and size is terrific

I use it for the same thing. I've only had it a few month. No leakage as of yet. Hope this helps. It works great on the back because it's size.

I've used used for several years now and just bought a second one. It's great. It does say 'cold-pack' so don't use it as a heat pack.

It should not leak. Mine does not. But it is, in my opinion, not a great idea to keep it pressurized all the time. Maybe a small valve at the handle would help.

I have three and they have not ever leaked in our back packs or beach bags. But if you flight check in inside your luggage, pressure will force it to leak.

I've never had a problem with it leaking. I throw it in a bag for the range and never think about it until I need a drink.

I have only added water on the initial setup. With this new one, the pillow part was not as thick as the first one I purchased about 4 years ago, so I had to add more water in the beginning. It has never leaked.

I personally haven't had any leaks. I think one of the reasons is that if you install the handle, it is very difficult to really crank down on the lid. I leave off the handle and seal them. Then place the handles in a baggy for later movement.

We love our water cooler, however the cold is really not very cold. We've been through a few, but will settle with slightly cold water as we haven't found one that cools the water well. As for the leaking, I would definitely get another one. Water damage can be a major problem. If I were you I would find which one has the best reviews for the price you're willing to spend and buy that one.

I bought one for the same use. Sometimes it leaks - not a lot, just enough to be irritating - sometimes it doesn't. I try to really tighten it down hard and that seems to stop any leaks. Just don't think I should have to work that hard! But the size and price point are both ideal!

It travels VERY well, but does sweat with very cold liquid. We use it daily and I have noticed after continuous use, if I shake the cup really hard it will leak a few drops. I does not leak during regular use or if left side ways on the floor.

A little, not much. I used mine 3 days a week for 2 months at work (desk job) before it started leaking. The leak was in the usual place- on the top where the bag is sealed around the rigid opening

I fly with 2 of them every week and have not had a problem. But the contents in them is more thick than thin. If I leave them in my checked suitcase I put it in a plastic bag. Overall, no leaks yet!!

I haven't noticed any particular leakage beyond what chair saws usually look like. Maybe there is a small crck in the cap. If you think it's excessive, try putting washer/gasket on it.

I have used mine extensively and have had no leakage. Here's an idea - if you are concerned about ruining a $1k+ laptop, go to Target or walmart and pick up a box of the HUGE ziplock bags and put the bladder in the ziplock bag as a secondary barrier. Hope this helps...

I use mine in the back of my pickup camper, in hilly terrain, rough roads, etc. Then down to the boat for a weekend on the water, absolutely no leakage!

I used the camelback bladder for a backpacking trip into the Grand Canyon. It held up very well inside the internal pocket in the pack. I did not notice any moisture inside. The humidity in the Canyon was near zero. condensation could occur if the liquid was cold and the enviroment humid. Th Camelback Bladder after all is just a medium thickness plastic bag that would be vunerable to puncture. I wouldn't trust it with my unprotected electronics.

I would stray away from this one. I bought it for long dirt bike rides where you can get extremely exhausted miles away from water. This one leaked since the first time I tried it. It was very cold out and my back was soaked. Also, the nozzle was a big let down. You actually have to open and close it like a pop-up water bottle. My buddy bought a fox brand water pack and has had it for over a year, on multiple rides. He has fallen on it and it has never leaked. His nozzle is also a great design. It is a soft material and all you do is bite it gently and suck. No hands needed. Hope this helps.

I gave it to my mother-in-law as a gift. I just checked in with her today to see how they are holding up. She said she uses them often and has not had a problem with them leaking.
