What is the opinion of Reddit about the
Braun CCR4 Clean and Renew Cart Shaver Refills, 4 Pack?

Never seen Clean and Renew things at Costco here in Seattle and have been using both for years. My solution has been to select the Amazon 4 pk and put it in a subscribe and save for every 6 months (sorry Costco). https://www.amazon.com/Braun-Cartridge-Replacement-Cleaning-Solution/dp/B007SNGSFS/
