I haven't read any posts that says everyone is experiencing issues with the 2Go.
The fact that Chord have already done a FW upgrade recently, with another one apparently imminent suggests everything is not perfect.
Who said it was perfect?
I owned to Polys and fully knew what I might be getting into. Poly, to me, was a complete failure of a purchase.
Luckily, 2Go is in a different league altogether. I trust that the Chord team are hard at work at making further improvements to the software.
