I bought this for a school project running around the hospital teaching CHF people. Yes, it's smaller than life size, but I find it very durable, which was important considering I'll be carrying it around for 6 hours and opening it hundreds of times. It served its purpose very well, my teacher liked that I didn't just print something off the computer to give to my patients and it's cute so it's in my room now :) it's colourful, detailed and inexpensive . I am happy with this little model
