Children love it
Love this! My children couldn’t stop playing with it. They began to ask more questions and looked at the veins in their firearms asking if the blood in their veins comes from their heart.

A great simple explanation of circulatory system.
I'm not sure why this gets such terrible reviews. It's not entirely accurate but it's designed to give a simplified explanation of the circulatory system for children. My husband is a firefighter and my daughter (4 years old) is fascinated with his work especially during his EMT course. This provides a visual for her to see the blood coming into and out of the heart and to provide a gateway to questions she might not know to ask. She knows a heart pumps blood and has something to do with a pulse this provides her something to experience to link those ideas together. It has a small activity booklet. I have no idea if there are instructions in it as filling it is pretty self explanatory, just take the pump off fill it and pump the fluid in. If the dye packs are empty or dry, I haven't checked mine, some red flood coloring will suffice. I think people might be expecting a bit much of a toy.

Poor quality
I bought this product to get a better understanding of how the heart worked. I read a bunch of the reviews and felt that it was worth a try. Every time I squeezed the pump air bubbles went in the tubes making it hard for the "blood" to return back to the pump. Because of this I could never see a good flow of blood moving into and out of the heart. The video on the review site looks like it is a good product but mine behaved nothing like the one on the video. I am returning it.

It leaks, but is functional
We bought this for my son’s project on the cardiovascular system. It worked perfectly to start, but started leaking after 20 kids tried pumping the blood.

excellent teaching tool
excellent teaching tool. The dye for blood is very realistic and easy to use. The 5 year old kids in class loved pressing the pump to fill heart with blood. Just wish the lungs didn't fill with blood!

DISAPPOINTED HEART PUMP MODEL
MY 5 YEAR OLD GRANDSON LOVE THE HEART. HE CAN TELL YOU EVERY BIT ABOUT THE HUMAN HEART. HE IS HOME SCHOOLED AND VERY VERY SMART. THIS MODEL LEAKS FROM THE BLUB THE RED DYE AND THERE'S NOT ENOUGH OF THE DYE TO PLUMP THROUGH THE HEART AND LUNGS. AS YOUR PLUMPING IT IT STARTS TO BE PULLED BACK INTO THE BLUB SO WHAT IS THE PURPOSE OF HAVING THIS HEART MODEL. SO DISAPPOINTING FOR HIM AND ME TOO.

Disappointed
It's alright(ish) but quality isn't good. There's no spare or replacement blood and although its says don't use food colouring, the manufacturer replied to my request for spares and instructed me to use food colouring
