Annoyingly fun! We used this in the office and enjoyed the show. Some of the sounds are too faint to get attention but others make up for it. Controls are easy to adjust the tone.

Multiple Noises. It was a perfect office April fools joke. Easy to use and set up.

I used this on my girlfriend and my daughter, drove them crazy. They kept asking me did I hear that noise. They spent all afternoon trying to find it. It was so funny. Great trick. It wouldn't work on me as my hearing isn't good enough to hear it in the first place. Place them in different spots in the house, room. Keep a straight face when your girlfriend, boyfriend, wife or husband says "What is that! Can't you hear it!"

They make noise as long as you’re doing it manual they do not work afterwards too bad we’re gonna be super amusing. What a waste of money.

Served its purpose, was entertaining has a few sounds to switch between. Emits sound every 10-15 mins.

These things. They are hilarious to prank someone, can quite literally drive someone mad. Small, last a long time on battery.

These are a riot. Drove my coworkers nuts. Then we tormented the students.

Doesn't sound like a cricket at all. But does make a computer chirp random. Not very loud, so if its hidden we'll you can barely hear it.

Doesn't make the classic annoying smoke detector chirp
