I really love cert. It smells super clean so it really gives me peace of mind that my home is clean. I hadn't realised how ineffective most other cleaners were until I read about Cert, my home was probably a germ disaster zone before.
I'm all for reducing plastic and trying to use refillables as much as possible, so dissolvable tablets are a perfect solution (and bulk buying them helps me to never run out too!).
No other similar product can promise the same level of cleaning so I will not be switching again.
