Review highlights

Reviews

Love it!!!

"Very nice, takes my roasts to a different level"

— richard v. (5/5)

Wow!

"What a transformation! It's like a whole new supercharged roaster! It's done in 1/3 to 1/4 of the time and I can hear the cracks a LOT better. Watch your temps and fan speeds, you'll be turning them WAY down!"

— Glenn C. (5/5)

"Great price and can hardly notice any blemish. The very top of the rim has a slight hump in it but does not effect the performance at all! Great product and shippingbwas fast and packed well!"

— Caleb (5/5)

Blemished SR800 extension tube.

"I could not find a blemish. Tube really extends the SR800 roaster usefulness. Better heat control. Great visibility."

— Tom F. (5/5)

Amazing value!!! Thank you

"I just got a SR800 recently and really wanted the expansion tube after watching multiple people roasting coffee with it on YouTube. I was thinking it was a bit more than I wanted to spend right away, but when I saw this deal, I felt it was worth the risk based on the other reviews. WOW!!! What a great deal and yes, it took me a solid minute to find the very minor blemish, that I could care less about as this thing is very nice and performs as expected. Great value, and a special thank you!"

— Mike F. (5/5)

Would recommend

"On the one I received I'm assuming the blemish is the small divot you have to look for at the top lip of the glass, (where the chaff collector goes on top) of about 1mm x 4mm. It does not impact roasting at all. Great value option."

— Michael S. (5/5)

Blem Extension Chamber

"Really nice! I can't actually discern that it's a bled. It increases the capacity of my SR540 and improves the evenness of the roast. After I had used mine for a while, I bought one for my brother too."

— sonny r. (5/5)

Blemish?

"I couldn't find any blemish on the tube that I could feel or see. I'm happy with this purchase. I'll probably pick up another before they go the way of the dodo."

— Carson (5/5)

"A must have for coffee roasting"

— William (5/5)

Great deal!

"The only thing I noticed was the small imperfection in the glass casting with zero impact on safety or function. Other than that, this unit is 100% functional and really is the saving grace to the SR 800 and 540 series of roasters."

— Trevor R. (5/5)

IF THERE IS A NEED TO FILE A WARRANTY CLAIM

  • We will need the serial number, found on the underside of the base unit, starting with 540 or 800.  
  • Shipping or mailing address
  • Contact Phone Number
  • Pictures of the damage if filing a warranty claim for a roast chamber or top assembly.

IS YOUR MACHINE NOT HOT ENOUGH?

  • Verify that you are getting 120-122 Volts to the roaster without any extension cords.  
  • The ambient air temp is not below 55*F.  Cool temps will result in low heat output.
  • Make sure your roast profile includes lowering the fan speed as the beans roast to increase the chamber temperature.  
  • Running too few beans can result in heat not building up in the roast chamber.  Minimum of  3 Scoops, 3 OZ, or  85 Grams for both SR540 and SR800.
