"The Extension Tube is a game changer. It cuts your time in half to do roast twice as many beans."
"My old roasting chamber cracked and it was time for a replacement. I was disappointed at the loose fit of the this new chamber. I guess it's not an OEM part. I can still roast with it, but it is wobbly, especially with my extension tube, and the lack of snug might also affect temperature control."
"Now I can roast a larger amount again"
"It's always good to have an extra or backup. The people at home roasting supplies are the best."
"I had placed a small order the day before, then I broke my chamber and needed a new one. They combined my orders so I only had 1 shipping charge and they didn't have to do that. 👍"
"These folks are the most customer service oriented people ever."
"When I broke my chamber a few weeks ago, I tried various places to replace. Found it here, bought an extra for backup."
"Works really well - no deposits on the glass walls, air bed keeps beans well-circulating."
"Thought this info might be useful The metal that sits inside the chamber is 70mm on the 540/800 then flares to 95mm. The 540 glass is 95mm tall. 800 is around 130mm tall. Early chamber metal that goes into the base is 70mm and glass is 95mm tall. Early ext tube is 65mm at the smallest point 540/800 ext tube is 75mm at the bottom or smallest point. Then they are only a couple inches different on length."
"Great service on phone and delivered promptly"
