Love it!

Perfect! I like that I can see the progress and use a stainless steel bowl.

I could never bake a good loaf of bread until now. My proofer was the answer to keeping up with the fermentation process.

My Folding Proofer & Slow Cooker Expreience

So far, so good. I look forward to using this slow cooker for something other than yogurt.

Proofing A+...Slow-Cooking C-...

This proofer is amazing. I use it weekly. We live in a 140 year-old home and the temperature---especially in the winter, hovers around 68˚F. Pop my refrigerated/fed starter in the proofer at 6:00am 86˚F and 6 hours later it's bubbly and ready. Throughout the mix/stretch 'n fold/bulk proofing processes, I keep the bowl in the proofer. Perfect results.
I have used the Slow-Cooker, but, honestly, was less than impressed. The heat comes exclusively from the bottom and does not "surround" the vessel. For that application, this product is not recommended.
Having yet to "ferment" anything, I will reserve judgement.
The folding aspect is very helpful for those of us without a surplus of counter space. I purchased the canvas case and store the proofer on its side in a cabinet. Even thought he slow cooker mode is less than satisfactory, I didn't purchase this proofer with that application in mind.
I will still give it 5 Stars, because for what I need, it works perfectly.
Caveats aside, recommended.

Primotenore, thanks for such a thoughtful and balanced review! We’re glad the proofer is doing exactly what you need for reliable starter and dough development, and that the fold-away design fits your space well. We appreciate the candid feedback on the slow-cook function, and we’re dough-lited it’s still proving its worth where it counts most!

Best Purchase in 2026

I have no regrets buying this proofer! It is amazing! Now my husband can keep the house at whatever temperature he would like. My bread is safe in its proofing box! Seems to rise faster than usual.

Elizabeth, we’re dough-lited the Folding Proofer is making bread prep easier and keeping your dough happy. It sounds like it’s rising to the occasion perfectly!
