I didn't get 10 gallon igloos I went with the 5 gallon system instead, but I just wanted to say that they worked perfect!!! The false bottom was amazing!!! I made a milk stout and it had 1 pound of rice hulls which are a famous culprit in the ole' stuck mash category, but not single problem with my mash tun/ HLT set up. Thanks for the great deal and great product!!!
