I needed an alarm for my freezer and chose this one as I thought it would be a little tougher would. Well I was wrong. For $25.76 I got a thermometer that doesn't even keep the battery in the case. The alarm was so weak you had to stand by it to even hear it. When I ran the wire through the door it broke the seal and caused the freezer to run continuously and the freezer temperature to rise. and turned on the alarm. I think I could poke a hole in the side of the freezer but that would void my warranty. I probably gave this little thermometer a high 2 star rating. Let's get back to Revain. thanks amazon
