I'm giving this a 4 star because of the condenser. Overall I really like this product. However, the design of the worm on top makes it challenging because the condensation drips all on the top. Also, the worm isn't big enough. I'll be building my own. That being said it's hard to find a large pot with a lid that seals properly enough to distill. This one really is nice and does exactly what I need it to do.
