I have been researching to compare the quick 861dw and tr1300a, but nothing is clear, websites have different information, so I contacted "Quick Global" BillJiang , who was useless, he didn't even read my question and was more concerned where did I buy the unit???, when I asked him just a simple question knowing the 861dw has 120lt/min as max, how much is the max lt/min for the tr1300a, is 70lt/min? 100lt/min?, he couldn't or wanted to respond and never heard from him again , with that kind of customer support , I decided to go for Atten ST-862D, they responded right away to any questions, and it is the same quick station with a better price.
