I use that 36a "integy" one, Its not really an integy, its from
http://www.eaglemodel.com/ the directions are in chinese and it doesnt even say integy anywhere, they must have just bought some distribution rights or something. You can use it 18a x 2 or 36a but not both. Its held up well and has a cool blue light lol. It is chinese junk, but works great with my duo. That rivergate looks more heavy duty but never tried it.
