works
if you have a small cabin, rv, extra building these work. I have both the 5 and 2 gallon for different applications. fits in tight spaces. mountable in every way I could think of. I run 45 psi on one and 75 psi on the other. they can handle the 1/2 line water pressure. no leaks. easy to install.

Good tank
Upgraded 2gal to 5 gallon tank on an RO system to be able to fill larger potable water containers. Worked great.

Nice add-on for a R/O filter
Recently installed an I-spring 4-stage whole-house filter and R/O system. Flow rate was very low due to 1/4" output from R/O membrane and relatively low pressure on Well Tank system. (most work at between 45-60 psi). This tank allows enough filtered water to accumulate down-stream of the filter assembly to that your flow rate is not impacted at the refrigerator dispenser or ice maker.

Great for a small pump with one faucet
This tank works well for a small pump and few faucets, like an RV or a weekend cabin. It was a great upgrade from the initial 20 oz. tank that the manufacturer recommended for the very small pump I started with. Within a few weeks I made sequential upgrades to my rainwater catchment setup for a small house and found that this tank does not have enough capacity to handle a 1/2 hp jet pump with 4 faucets (upgraded to 14 gallon pressure tank).

Works well
I mean it's just a tank with a rubber air bladder, but it seems to work well so far.
