    Works for rats!
  

*by B***E on Reviewed in the United States on May 26, 2017*

I have pet rats.  I knew they vocalize ultrasonically, but I had never heard it.  Now I know -- they are as noisy as birds when they play, I could just never hear them.  They must think I'm deaf.I found out that you make ultrasonic sounds when you rub the tips of your fingers together.  Using this device, I've learned to make a sound very similar to their chirps by gently rubbing my thumb and pointer finger.  I can get their attention now without stressing them out, which is awesome.I was also surprised to find what stuff in my house makes ultrasonic noise.  My wireless router practically screams all the time.  More avoided stress for ratty friends, and kind of cool in its own right.The case is just 3D printed, but is plenty strong enough for everyday use as long as you don't abuse it.  The internal electronics seem to be well designed.  It doesn't seem to have a problem with interference from audible frequency noise in a room, but was sensitive to ultrasonic and near-ultrasonic when I tested it with a phone app.  Given that this is a small fraction of the cost of every other bat detector out there, it is a very good value.

    Not worth the price
  

*by T***Y on Reviewed in the United States on December 11, 2016*

Much much smaller and much more cheaply made than I had expected. Bought it as a birthday gift for my daughter, but am hoping to have to find something else to supliment it. Absolutely not worth the $30 price, feel very unhappy

    Experience the secret world of bats!
  

*by C***B on Reviewed in the United States on August 21, 2016*

This is a fun device, for a reasonable price.  I am what the Brits would call a "bat enthusiast" and there's nothing better than spending some time observing them at dusk from my deck on a summer evening.  This bat detector takes the ultrasonic echolocation calls that they use to find their insect prey, but which are too high a frequency for humans to hear, and steps down the frequency to one we can hear.  The patterns of the calls (different for every species of bat) are retained so you can hear the clicks, trills and feeding buzzes clearly.  The only problem I found is that the built-in speaker is too quiet and it's hard to hear well.  But, the unit has a headset jack which I use to attach a small external, self-powered, volume-adjustable speaker with a standard 3.5mm double-male end headphone jack.  That way, I can adjust the volume to whatever I need.  Teach your children, and your friends, about another fascinating aspect of our natural world by having a bat-watching event before summer ends.  Here in western NY, we probably have another month or so of bat activity before they head off to their winter hibernation sites.  Further south, you've got more time to study these wonderful animals.
