Shackcom shelf liner

So far this has stopped a flood about 5 times (only using one at the moment), I have an intermittent blockage, which I have yet to track down.

Really good leak alarm works well great price

cheap and good

This works very well and has saved my laminate flooring when the washer started to leak - the alarm went off long before there was enough water to cause any major damage.

Easy to set up and use.

All good

Initial one got lost in the mail. Just received the "replacemnt" and installed, so no idea yet of the oveerall performance. Inittial impresson is positive as it tested correctly- very loud. Does not come with the 9volt battery so that needs to be ordered seperaely it you don't have one. I would recommend it.

I bought a bunch of the Zircon water leak detectors and was not impressed. I literally had to duct tape them together after putting the battery in because the tops were so loose. And when I tested them, the beep beep beep to signal a leak was not loud at all. If you had the alarm under the sink with the cabinet door shut, you could kind of hear it if you were close by. If you were downstairs, forget about it. So I bought some of these.WOW, that's loud!!! Loud like walking by the fire alarm back in grade school loud. There's no way you're missing this, even if it's behind a pack of toilet paper and the cabinet door is closed and you're downstairs. If you've got a leak, you're going to hear it loud and clear. I did put a brand new Energizer in it, as new top-line batteries are recommended. The thing is sensitive and seems to work well. I'm pleased.

Well, there's not much of a choice in this product type. However, this one jumped to the top of my list. They are as they appear, what I'd say is heavy duty. They do what's described, and well. I wish I'd known of these years ago, - if even existed. So, I use three, two for groundwater rise that comes from water shed, so, we get wet from the ground up, not surface and not a high water level, "normally".Also, since have a water heater that needed T-stats changed, we stuck one in the overflow catch bucket to let us know of any issues, possibly prior to it's overflow. We're not sure how it may hold up to the water heater hot water, circa 110F ish but we guess it may be okay. And, if works as an early alarm, I'll guess, it will be fine.So, at this quality and price point, - good value.

The unit seems solid, it is loud when in alarm mode and the red lamp will be helpful in the dark. One concern I have in the design is to place the 9v battery inside the unit you unscrew the top from the base. The wires inside are a very light gauge and when you are screwing the top and bottom to get the unit apart the wires twist with the action of unscrewing. Hopefully the battery replacement will not be often enough that these wires will break or twist themselves free. Again, this may not bother some people but do be careful when unscrewing!

I've had Watchdog water alarms in my homes for many years...and they have saved my bacon twice...and if you need a thin alarm to fit in a tight space...or you need to locate the sensor several feet away from the alarm, the Watchdog is a good choice.But, if you are looking for an alarm with a really loud and annoying signal that you can put in a bathroom sink cabinet and still hear...or if you are looking for an alarm with an attention grabbing flashing light...then without a doubt the Shackcom Basement Water Leak Detector Alarm should be at the top of the list. You make think the alarm itself is kind of cute...like a little robot, or you make think it ugly like it belongs in a plumber's box...but the volume and the flashing light really carry the day.The alarm is small...about 3" in diameter. Screw off the top (which opens easily), plop in the 9v battery and you are good to go. You can test it by moistening your finger and touching both electrodes...remove your finger and the alarm goes silent. Just a tiny bit of water on the floor and the alarm goes off...and if you want to enhance its ability to go off, just place it on a small paper towel cut to size. The towel will quickly absorb any water and voila, the alarm goes off...and did I say it is really LOUD (which is what you really want).Very highly recommended....in fact, I will buy a few more of them for other locations in the house. I've included a photo of the instructions that come with the alarm.Final note, The alarm I'm reviewing is the 9volt model. Shackcom also sells a floating alarm in a multi pack without the light...I'm not sure how well this product performs although others have said it can be difficult to screw the top off)
