In July I saw a homebrewer complaining about the InfuSsion mash tun on HomeBrewTalk. So I offered to send him the ThermoBarrel for comparison to see if he liked it any better. The deal was that he could either return the ThermoBarrel or trade me the InfuSsion tun.
After several brews he ended up keeping the ThermoBarrel and sending me the InfuSsion tun, including the accessories he had bought for it. Bottom line is that he chose the $320 ThermoBarrel over a mash tun he had spent $475 on. See all the reasons why he chose the ThermoBarrel in his video comparison here.
