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.

Can’t get it open.

We CANNOT get the screw out to put in batteries! Can you send me another?

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.

Have to manually turn off-no timer

Just okay. It works, but my other units are on a timer and turn off themselves. This doesn’t shut off unless I manually turn it off so the batteries don’t last.
