This has made it so much easier to get my starter and breads to rise despite the outside temperature fluctuations. Helps me to stay on schedule.

Pratique et fonctionne très bien

I purchased this box after experiencing many bulk fermentation issues for weeks. After a popular sourdough baker talked about it on social media multiple times I thought it would be the answer to my proofing problems. I also liked that it folded flat for storage and I could control the temperature as needed. After trying it roughly a dozen times I realized I wasted my money. The included instructions were not helpful as to temperature, so I turned to YouTube for guidance. Not much there either. I figured I would set it at the temperature most sourdough bakers recommend which is right around 75. Each time my dough remained sticky and either under-or over-proofed; never just right. I even went so far as to set a timer for 30 minute intervals so I could check on it regularly. After a full day of fermentation, I could not get a decent dough. The rise was great, but the stickiness never went away, and I was unable to shape it. Either that or it would rise and then collapse, although I was checking it on a regular basis. So now it sits folded up in a cabinet, and in my opinion, a total waste of $250. I guess I will return to my original method of letting it rise in my laundry room on top of the dryer. Lesson learned.

it makes bulk fermentation so much easier and faster usually done in about 4 and 1/2 to 5 hours.
