These tablets are LEGIT!!! I have literally spent HUNDREDS of dollars trying to get the "stink" out of my front loading washing machine without any success. I promise you that amount is NOT an exaggeration! Maybe I have a sensitive nose or full blown OCD, but the funk from the front load washer is real! We have 2 long haired cats which I assume is the biggest part of our problem. It had gotten to the point that I was almost having to clean my clothes before I even washed them! I am not even kidding. The amount of money I have spent on lint rollers alone could put a child through school. So when I say these tablets genuinely worked, I am so truly thankful to have found them!!! I have purchased all the major brands multiple times - Tide, Affresh, LemmiShine, Uproot....you name it, I tried it. I regularly deep clean my machine by cleaning the inside rim, wiping down all interior surfaces including draining the plugs at the bottom of the machine. I would then run one or two "Tub Clean cycles" on my washer (with one of the fore mentioned cleaners) and while it was improved, it still had that funk. NOTHING seemed to work longer than 1 or two loads of laundry. And I promise, I was "deep cleaning" at LEAST once every 3-4 weeks. This is just WAY TOO MUCH. Nobody's got time for that! When I saw these tablets I was HIGHLY skeptical because I have literally tried them all and none of them really worked. I figured I had nothing to lose and I am SO THANKFUL that I gave them a shot. They are beyond easy to use. They are individually wrapped and instructions are super straightforward. Just open the package and toss the tablet in the drum of your washing machine! That's it! Easy peasey. The box even has a tracker so you can record each time you use them. I admit, my first time using these I put 2 in the washer (because that's what I would do with all the others). I ran the clean cycle and hoped for the best. The difference was instant!! The wash was foamy (which to me says it's getting into all the books and crannies as advertised). Never had this level of foam with any other brand. When I opened that door after the cycle was done, I couldn't believe my nose!! FRESHNESS!!!! A smell I haven't smelled in my washer for way too long. I literally just got these 2 weeks ago and have only used them the one time but I have done AT LEAST 10 loads of laundry since and my washer is STILL FRESH!!!!!! I am so incredibly sincere in saying BUY THESE TABLETS if you are a household with pets or sick and tired of a stinky washing machine. These legit changed the game and I will always have them on hand. Buy them now!!
