Perfect multi-use water tank
Color: Blue
Great Water tank! We got it to put in our storage room for emergency preparedness but are debating getting a second to put in our in home gym to use as a water station! The color is a perfect dusty blue and the size is great for smaller areas (picture in comparison to a 18 Gallon tote). The spigot is metal and feels super solid like it is built to last! Love that the lid on the top is big for ease of filling! Also really excited that they are stackable for future purchases to stack on top! All in all we love this tank and would highly recommend it for your water storage needs! ... show more

Very well built! Great buy for the $$
Color: Blue
Very well built! Much higher quality than what I was expecting. The plastic is thick and durable. I filled it up with water and tipped it over and it had zero leaks! The lid fits perfect and tightens right down. Much better quality than others that I’ve had. I plan to buy more. Would definitely recommend! ... show more

Water storage

Great quality but does have a smell

Sus plastic
Color: Blue
This thing smells toxic as heck. It's extremely strong-smelling and not something I want to use for storing drinking water. I'm also wondering if the spout is made with ABS plastic. There is no discernable marking for a safe plastic on this thing, stay away. Now returning, it's a hassle, so big. I tried airing it out, and even rinsing and washing with mild dish soap and a brush, but no change to the extremely strong chemical odor from this plastic "water" tank. ... show more

Perfect size, well designed water storage tank
Color: Blue
This is a perfect size water storage tank! Love the ability to add more tanks and that they are stackable! The square design is great too vs the traditional round barrel tanks. No wasted space when storing stacks of these side by side. I also like the size of just one which opens up many options. I plan to take it with me for portable fresh water for all my outdoor off grid adventures. Construction is very good! I love the brass spicket that is also solid. Also shipping was faster than expected. Very organized company! Overall I give product and company 5 Stars! Highly recommend this product and company ... show more

This water tank has been awesome!
Color: Blue
This water tank has been an excellent addition to our emergency preparedness plan. The construction feels incredibly durable and well-made, giving us confidence in its long-term reliability. It’s also the perfect size for our basement, fitting comfortably without taking up too much space. My wife and I have been looking for practical ways to improve our emergency readiness, and this tank has been exactly what we needed. ... show more

I guess Emergency water storage would be ok........
Color: Blue
When the tank was completely filled it bowed out (lost original shape) slightly. Not sure what it would do when stacked. The gasket from the top lid fell in while trying to secure it. (kind of irritating) The chemical smell wasn't overly strong but skeptical on how many gallons of water that would be needed to wash it out. With long term storage I would think that it would add an off taste. ... show more
