Setup was easier than I expected. Took me maybe 10 minutes and didn’t need any tools. The float valve works well so far — no more worrying about my humidifier running dry. The bucket feels sturdy even though it’s collapsible.
Amanda Brooks –
I was worried about leaks, but so far it’s been solid. The tank feels sturdy and the float system is very simple. Using it in my grow tent and it keeps the humidifier topped off without overfilling.

I was skeptical about leaks, but this kit is rock-solid. No mess after a month of use. Worth every penny!
