Great addition to Hydro Flask wide water bottle.  Makes carrying the bottle much easier...it really does.  Super easy to use and imposes no additional inconvenience/burden on you.  Highly recommend these handles.

Easy to install.  Great addition to a Camelbak hydration bladder.  I'd recommend buying one.  I'm not sure why it isn't standard on every Camelbak bladder, but it's an inexpensive and useful addition.

Well made, easy to install, works well, saves lots of water. Only regret is not having installed this earlier .. ;-)

worked perfectly for our shower and takes just a few minutes to change it out.  It fixed our issue of having very low water pressure.

I have been using this water changer for over 6 years now. Still works like new and have never had to replace any parts. Fit on sinks in 3 different locations. Tried the Python before this and did not care for it. Don't miss the buckets!

Works great and really easy to add to the tank to make sure the PH is high enough for the tank creatures.

Works flawlessly.  Night drop option simulates ball python natural environment.  I currently own 2 and ordering 3rd asap.  Must have for any snake owner with rack systems.

Works great with my tankless water heater.  (This is the same unit that Rheem sells under their own branding)
It was easy to install, took about 40 minutes with a minimal set of tools (2 wrenches, basically).  Worst part was going up and down 2 flights of stairs to turn the water off and on.  Now instead of waiting 90-120 seconds for hot water, it's right there.
I used a z-wave plugin paired with a z-wave motion sensor to turn it on and off.  The Smartthings hub has a rule to turn on the plugin whenever it senses motion between 6AM and midnight; and to turn it off after 5 minutes of inactivity.  Seems to be working great, and its nice to be able to tweak the settings if I want to.

I added this to my system when I installed it. It took the 7.0 ph output to a 8.0 ph with no change in the taste of the water. It was easy to install and fits snug to hold it in place.

This 45 degree adapter worked perfectly with no leaking. It provided better flow, clearance of black and grey water valve handles, and is clear to allow visual indication when your tanks are properly clean. Highly recommend this product.

Great product and works great with the new filter system. Gives plenty of length to backwash my pond's filter. Not cheaply made and seems to be of good quality.

Does exactly what it said. Keeps the tank very clean. Easily adjust the flow for feeding.

made water changes super easy, I feel the connector plastic can be a little stronger than it is right now but works great.

Works great, it has made cleaning the tank so much easier and cleaner than the traditional syphon I had been using. Good product and good price.

This thing makes water changes a breeze. I love that it has a garden hose connection eductor pump that also comes with a faucet adapter. This allows you to pump the water and debris out and dispose of it automatically down the drain. And, with a quick flip of the bottom plug on the faucet pump it becomes a fill line for refilling the water that was removed. The other nice thing is that this generates more vacuum than simply siphoning the tank out using gravity, so this works very well.

The fittings, valve, pump and the vacuum tube are all nice and well made parts, not cheap junk. I am not sure what size the tubing is but it is heavy wall thickness tubing, I think you could probably buy more of it at the hardware store. The fittings that it comes with are nice as well.

My original sump switch (which was a cheap vertical float) went bad, I had originally bought one of the tethered float switches that is zip tied to the output pipe and then inverts as the water level rises. That needed a lot of room and was prone to be constrained by other things in the sump well.  This Watchdog Dual Float has none of those problems.  It has...
Substantial build quality
Isolated in a compact cage that eliminates any interference.
The switch is intelligent and keeps the sump running a few extra seconds to fully drain even though the float switch is mounted several inches above absolute bottom.
