Heartbeat machine
Not what I was expecting. Pretty small and you can't really hear it. I was hoping to put it up on a shelf for my dogs when I leave. But, they'll never hear it. I'm sure I can use it for something else. Just not what I was hoping to unfortunately

Great replacement heart for bear toy
Many years ago I bought a Heart to Heart Bear (1980s)--with a heartbeat. After several years the heart stopped working, but I kept the bear--thinking that some day I could fix it. Last Saturday I replaced the original heart with this heartbeat toy and now she works great! The heart is not too loud and the fact that I can start and end it without opening the bear is great. I am going to buy another one as back-up just in case this one stops working. Thank you.

Calming with a pulse
I bought these to transport puppies across the US. I put one in each carrier and the puppies slept on each plane ride. A total of over 5 hours on planes. Would totally recommend.
