This larger KneadAce Pro Jar is perfect for adding my rye frige starter to, add water & a little more rye, then letting it overnight rise, then bake with next morning. It's sturdy, has quality/useful accessories, is easy to mix in, has room for this starter rise, & easy to clean with the straight jar neck design (no hip on jar like my old Mason jar). I bake 6 loaves at a time monthly & freeze most of it for later use. This Pro Jar certainly makes the task easier to prepare enough starter for baking & comes with everything needed.

Also have the standard size Jar for my rye starter fridge storage. Great company line of products!

I love this jar! It's much easier to add to and stirring is much easier then the mason jar I was using. I love the band with days and times in it so I don't have to actually engender when my last feed was!

I really liked this product. The jar was nice and the flexible band to help time the feedings is awesome. The silicon tool is great. However, the glass is not very strong or durable. While doing the dishes, a glass bowl tapped the rim of the jar and a huge glass chunk flew off. It is now unusable after only two weeks.

EDIT: after posting this review, the seller contacted me personally and offered a replacement kit at no charge. I was very impressed with the customer service and will be giving it another chance.

The sides are slanted , making it difficult to keep sides clean.

I am very pleased with the KneadAce Pro. I kept a sourdough starter going for around 30 years. Family health issues required a lot of my time and I stopped baking. This year I wanted to start again and notice the KneadAce Pro at Amazon. My first thought was, I don't need this. I can do what I did before and use a bowl and cheesecloth. But, the product looked very interesting and I decided to give it a try. Wow, I am so glad I did. Having a product specifically designed for making a sourdough starter was so easy. I love having the temperature gauge, which I didn't have when I was making sourdough before. There is a spatula provided that is a perfect fit for the KneadAce Pro. The band with days listed on it is perfect and removes the need for magic markers. I was shocked when my starter doubled in size by the end of the second day. I never had that happen before. I thought it was a glitch, so I gave it another try and the same thing happened a second time. I still went through the week to build the starter, and that was so easy too. I can recommend the product for anyone interested in a sourdough starter.
