The black button is on the left side, not like in the photo, on the right side. To insert the batteries (2 AAA) you have to remove a screw. By pressing the button you hear the heartbeat, a bit robotic, but it all depends on where it will be placed. Maybe inside the plush it will be fine. In the end, I recommend it, it's a curious thing. I'm going to try it.
as ordered
The hearts themselves sound quite mechanical, but after hiding them in the bear, you can only hear a nice heartbeat. I recommend it!
Perfect, exactly what I wanted.
Happy with purchase and fast delivery
Very good, it has a timer so that's fine.
It's quite nice, but the button is very difficult to press.
My dog is afraid of it. put in a sock under a blanket, she dug it out. even put it in a stuffed animal - the animal is now a chew toy. it would probably work better with a baby
Wonderful! It has a slight heartbeat sound that simulates it very well, I love it!
Very satisfied with the product, it is exactly as advertised, it arrived very quickly, I recommend it without a doubt.
It sounds like a spring, my dog didn't like it, I guess it's not for all dogs.
very good but made a lot of noise
I'm not quite sure if that's supposed to be that loud and vibrating...
Super
Perfect! I have got so many teddy bears at home. So i just needed the sound effect. It works perfectly and i can't wait to see the reaction of my puppy.
Unfortunately, it no longer works 😕 my dog playing with his plush toy, where I put the heart, hit it and it stopped working 😥
