    “George, Thank you for your time. I have downloaded the [competitor's] manual and programmed it according to directions. And have to say their manual is no where near as helpful as yours. And then I verified that the correct numbers were in there, and it still does not work. Since this is a new purchase of the locomotive I have contacted [the locomotive manufactured]. Because as far as I can tell [the decoder manufacture] really doesn't have support, they direct you to forms. And I tried to find WEB support and couldn't find it. I will say this I will never purchase a product again that has [that] decoder... And I will say you have been very helpful and I would not hesitate to purchase a locomotive that has your decoders in it. ”
    -Again Thank You Richard
  • Competition Comparison 1
    ““I have been a big [competitor's] fan, but after working with the Tsunam2 decoders for a while now, I am convinced they are the absolute top of the group out there. They have much clearer sound files than the [competition] in my opinion.”
  • Competition Comparison 2
    “ I was a hard-core [other decoder brand] guy and while I still like and use their products (mostly...with my European trains) you have showed me that the T2 is more than a worthy competitor to the [decoder] when used with North American models. [The other decoder] does have a nice independent brake but they have nothing that compares to your DDE. As a former audio engineer I will also say that the amplifier you are using in the T2 seems to produce more volume and with much less distortion...
