I've held off reviewing for a few weeks - now I've used the sponges properly, I can honestly say they're amazingly good! I work as a professional cleaner, and use them both for client work and in my own home. Yes, they're a bit expensive compared to regular sponges, but I do think we have to try and do what we can. Every little helps, and I feel like I have to do my bit. The loofah is just the right amount of scrub, and they rinse clean quickly. The pop-up expanding sponges are also great for wiping up spills, and although the white will show stains quickly, you just bung them in with your whites wash and they're all good as new. Brilliant! Definitely a customer for life now.
