Jobo 4061 レトロE6キット（CPE-3用）

The snug fit keeps each bottle from rattling during the warming cycle, which was my biggest annoyance before. Temperature stays consistent across all six, so no more worrying about uneven chemistry.

My six E6 bottles finally stay put in the CPE-3 instead of rattling around, and the snug fit means they’re all sitting in the water bath at a consistent temp. Honestly, this divider turned a fiddly setup into a five-minute job.

The six bottles finally sit still in the CPE-3 instead of sliding around, and the temp stays even across all of them. It's a simple piece of plastic but it does exactly what it's meant to, which is more than I can say for my last setup.
