ZERO Star Rating!
Please DO NOT Purchase this product for demonstrating pumping of blood in heart. You may use it just to show a 3D diagram of heart and lungs connection_ but the pumping model does not show the difference in oxygenated and de-oxygenated blood nor does it show how the blood is pumped from one chamber to another and then to the lungs and back accurately (not even remotely accurate). The simulated blood (red-colored water) just flows erratically with NO resemblance to how a heart pumps blood. I wonder who designed, tested and recommended this product!

Much room for improvement
I bought this for use with my children whom I home educate as I had planned a topic on the heart. The concept of a 'heart model' that demonstrates the main heart function is fantastic but unfortunately the product has two main flaws which left me feeling rather disappointed: The lungs fill up with liquid - This is a design flaw as fluid on the lungs is not demonstrative of healthy heart function and secondly the air bubbles also add an inaccuracy. I think the two flaws draw away from the benefit of this resource. I also found the pumping action was not easy and it had to be held at a certain angle to maximise efficiency. In general I love Learning Resource products but this one has left me feeling rather heart broken :(
