"Impressive performance. Tested the Great Poseidon! as soon as I got it. Placed it in the bathroom then poured a little of water near it, which flowed to and touched the device. As advertised, it let out a pretty loud alarm. Definitely ordering more." Jim McDonnell, Buffalo, NY
"The best timing ever. Just a couple of weeks after receiving this we were alerted to a leak in the basement in the middle of the night. My husband was able to fix it before it got worse. The timing is crazy! I am very thankful for this product!" Jennifer T., Bloomington, MN
"Worked when tested. The alarm worked when I placed it in a shallow puddle from a hose in the garage! It feels sturdy and well-built as well, needs only batteries to run. Great item." Paul Craig, Norfolk, VA
