Review: Good if your fridge does not have an audible alarm and people won't close the door properly! - Purchased for a fridge whereby people were leaving the door open, then it would ice up and muggins me would have to clean out excess water. Picked this one based on reviews. With some trial and error to position the unit and sensor, it now works very well. I used white tack to fix the 2 parts to the fridge. Surprising how even 1 or 2 mm difference in position could have it alarming, so white tack was a good solution. Spent maybe 20 mins to sort out the alarm I wanted and to position it on the fridge, it has been working well and alarms if the door is left open more that a few millimeters. The alarm volume is good.
Review: Works great. - Very easy to install. It has different timer options and very loud alarm can hear it from across the house if door is left open. Life saver if you have kids!
