When I first came across this extension tube I was highly skeptical that it would make a difference. After receiving it I immediately put it into action and was pleasantly surprised. Let me first say that I have been using the same SR500 roaster for about 6 years now and for whatever reason it seemed my roast where inconsistent. I have my eye on a new roaster but my piggy bank isn’t full enough yet (Hottop KN-8828B-2K). So I decided to try this tube to see what it would do. I can roast about twice as much as I did before with much more consistent results. The beans really move through this tube and this has extended the life of my SR500. Inconsistent roast do not work for me. Well worth the money for me! I also want to say Coffee Bean Corral has excellent customer service and really nice and knowledgeable people.
