Durable and reliable

I've used this core for over twenty rolls now. No signs of wear or chemical degradation. It's exactly what I needed to keep my darkroom workflow going.

Perfect fit for my JOBO tank

I was worried about compatibility, but this core fits perfectly into my existing JOBO reels. The plastic feels sturdy and handles the warm chemistry without warping.

Great value accessory

For the price, you can't beat this. It allows me to use my vintage JOBO tanks with modern films without any issues. Fast shipping too.

Works but tight fit

The core functions as expected, but it is a very tight fit on my older Paterson spiral. I have to push quite hard to get it to click in. Once in, it's fine.

Essential for double reel setups

Bought two of these to run double reels in my deep tank. They spin smoothly and lock in place securely. Highly recommended for serious developers.

Good replacement part

Lost my original core and needed a quick replacement. This works well with Paterson tanks too. Only giving 4 stars because the finish is slightly rougher than the OEM part.
