I've been using the unscented dish soap puck for over 8 months, and I like it! When I originally moved into my apartment, I did get a bottle of liquid dish soap out of necessity because I hadn't had a chance to stop at Green Life, but I did have dirty dishes that needed cleaning. I have hardly touched the liquid dish soap since getting this solid bar, with the exception of using the liquid dish soap on grease stains in clothing once or twice:)
I am about halfway through my first puck, and I do dishes almost daily! I do not do as much cooking as some of the other reviewers, but I think this dish soap cuts through grease just fine. I do pre-rinse my dishes and let them soak for a while if they have any food that's really stuck on, and I've never felt that this dish soap isn't getting them clean. In fact, I have a dishwasher but have only used it two or three times since moving in—I feel that washing my dishes by hand with this soap and my dish brush gets them cleaner than the dishwasher!
When I need to replace this, I think I will try the lemon-scented puck, although I did see a review noting that the scent is barely perceivable. Either way, this dish soap puck gets the job done for me!
