Works exactly like it should and no leaks

Works exactly like it should and no leaks. I have a whirlpool duet for reference. It was slightly different from the original but fits pretty much perfect. Some reviewers said theirs was noisy but mine is not. Since I got the washer and dryer for $75 I definitely don't mind paying the amount I did for this part.

Works perfectly and I took it diving last week and it worked underwater (not measuring steps) and didn't leak. Syncs with My Fitness Pal as advertised.

Works perfectly. No leaks. I'm happy not to pour water all over myself anymore.

Works great, no leaks at all. However I did attach the clear plastic to the hose the first time and had leaks but that's because I didn't read the manual thoroughly.  Wish it had a better cable management system overall.

This device was purchased to replace an ancient one tbat looked nasty and leaked. We couldn't find one in local stores that were the right size or didn't leak because of being warped  by poor packagjng.
This one holds water for as long as you want it to.  Simple,well done,works

I know there were some negative reviews on this product, do I wanted to wait and use mine before I gave my 2 cents worth.  I've had it up 3 months, and it still works flawlessly. No leaks at all. It looks just as good as it did when  I took it out of it's packaging. I'd definitely recommend this dispenser. It's the perfect size, doesn't look industrial... I love it!

Works great, no leaks! I purchased this for a Kenmore 665.17439001 portable dishwasher. Thanks to other reviews on Amazon, I got the idea that this Plumb Pak adapter was a better option over the manufacturers part. They were absolutely right. Priced right as well!

Fits perfectly, nice snug fit so no possible worries about leaks

This works exactly as you expect it would. One nice feature is the screw on cap that leaks the water so you have less of a mess to deal with while flipping the container over.

This bottle, when filled and used properly, doesn't leak at all. It is made of a thicker plastic than pet store cheapies so it's not as pressure sensitive. Anyone who's owned water bottles knows if the bottle is squeezed, it loses some of the vacuum which results in leaks.
Because my male rat is solo in his cage and doesn't chew plastic, I used the holder from my previous glass bottle along with the included top holder to mount it inside his cage. This eliminates any possible pressure on the bottle.

To use:
Fill all the way to the top, to the point of overflowing, and fill the nozzle end with water, too, to wet the gasket. Screw nozzle on snugly and flip the bottle. Squeeze the bottle a little and tap the ball with your finger a couple of times to establish a vacuum seal (you'll see bubbles going up). Put on cage and tap a couple more times. Good to go!
Use a baby bottle brush to clean the bottle and nozzle each time you change it and this bottle will years!

It works great (no leaks) and it fits standard 3" PVC pipe

This thing works great. I keep my spigot open all the time and use this as the on/off valve. No leaks. The knobs are a little stiff and might give someone with low hand strength some trouble, but otherwise, no complaints.

Works great - easy to install, very durable - and the best part is no leaks.  I ordered a second one.
