I was weary at first to purchase this kit because the price was a bit high. But as it turns out it was worth every penny. I bought this for my 4yr old and she loves it! It is well made, light weight, sturdy, no small parts that fall off. The blood preasure device is sewn very well and will stand up to to being attached and reattached many times. The stethascope makes heartbeat sounds and the earpieces are soft and oversized so they won't harm your child's ears. The pager beeps like a real pager and requires 2 AAA batteries. The case is big enough that you can add more to it.
