Very nice
Pretty good idea and great design. I couldnt belive it.. The price was reasonable and i thought its probably just a clicking clock type thing, so my hopes werent really up, but i figured i would give it a try, i was so amazed when i turned it on. It actually feels like the gentle thump of the heart beat. No clicking like a clock or anything you can imagine up. Im very impressed. My dog is adjusting to being blind so she wakes up scared and confused and cries till I can get to her and reassure her. I put this in her blanket with an small hand warmer and it has had a calming effect for her. She can feel the heart beat vibrate through her blanket and pillow and the low warmth of the hand warmer is comforting.
The charge makes it through the night so if I go to the kitchen or do a chore she is comforted when I'm not close at hand.
I'm ordering a second one so I can alternate them, one charging while one is in use. I can put this in her stroller and should I need to charge it it works off of the phone charger in my car or even the extra chargers we have available every where.
Very well made, nothing that could break off and be swallowed by accident. Nothing that could stick her or injure her at all. Smooth to touch, button is level ,no way to dig it out or chew it loose.
Nice to receive a well designed product that I can trust is safe for my babis. Cause yes.... we want the best for our pets.
I give this my highest recommendation. If they had a number higher than 5. This little gem would deserve it. Only the best my jenny.
2nd purchase addendum:
Awesome!!!!!
I decide to give this gem a real work out. I charged it up and put it in Jenny's blanket and let it run.... 36 hours later it was still going strong. You can feel the lub dub heart beat on top, a foot away and 2 feet away. Jenny sleeps in bed with me so I felt all around it and could feel it through the blanket and into her pillow. Sometime she lays on top of it, sometimes she is beside it but she is always within it's range. I removed it to charge and she searched for it and couldn't settle and calm. So I ordered a second one. One is charging while the other is in use, i could feel the gentle heart beat through the mattress. It's not annoying, just a soothing heart beat she finds comfort with.
I can place it in her carriage or in her travel carrier in the car. Fits in the palm of your hand, not bulky or uncomfortable.
It lights up when it is charging and goes dark when the charge is complete. I took it with her when she went to the baby sitter (usually she is always with me) and she was comfortable the short time I was gone.
Wouldn't be without this gem. It is well made and safe i give it a 10. Best thing you can get for your babis. You won't be disappointed. ❤️

Good product.
Works well. Holds a good charge. Helped my puppy some. I put it in a blanket that smelled like her family. Seemed to help her sleep better than. Some puppies in the past. Durable when she does get her teeth on it. Also a good size.

I use it for myself not my pet
I sewed a fluffy velcro pouch to put this in, and then I wrapped the pouch around a microwavable heat gel pack in order to get the sensation of both heat and heartbeat while hugging a large stuffed animal. It works great. It's not too loud if you position it right. It helps me to fall asleep and not feel lonely or touch starved. The battery lasts a long time and I don't have to recharge it very often. I only wish that the speed of the heartbeat was adjustable so that I could slow it down a little more so that my own heartbeat might try to match it.
