Doesn't Work At ALL!!!
I've used 4 tablets! 2 first run, 2 second run, did it right after I received the package.  Was excited,  but after "results" got disappointed! Have no idea where those reviews coming from! Come one Amazon, test product your self first and them rip off people! Just wasted money to a septic!!! PLEASE DONT BUY, just Google how to clean kettle at home, that will work better than those worthless tablets!
