Just got this hyperglycemia vs normal blood flow model for my clinic, and it's been super helpful already!

The 3D-printed red blood cells moving through the tubes really grab patients' attention. I've noticed they ask more questions when they can actually see the difference in flow speed between high and normal glucose levels.

As a healthcare educator, I appreciate how it simplifies a complex concept. The eco-friendly materials are a nice bonus too - no weird chemical smells like some educational models have.

One small issue: mine arrived with some liquid displacement (like another reviewer mentioned). It's not a dealbreaker - just needs an occasional shake to redistribute properly.

Worth noting this isn't a toy despite the cool visual aspect. The educational value for diabetes patients makes it worth the investment in my opinion.
