I find with that site is that they really have no idea what they are talking about. These guys have no clue and that dryer review proved it. Not to mention the dishwasher reviews and washer reviews. They make no mention of what detergent they are using for either type of machine because that will impact the results greatly. Lets say they are using Xtra liquid for a washer test one will get dismal results, now if one used Tide HE powder or Persil Universal , results would be drastically different. Same with dishwashers, my go to now is Somat Powder loaded with phosphates, results are outstanding. Or even the new Cascade Platinum results are very good, use a gel and results might be spotty. I have read a few reviews and they are lacking common sense. Don't get me started! Lol
