Tuning box long term?

[exiged]

These have obviously come on a long way now with the addition of the 3rd channel for rpm sense.

Im not looking to start a box vs remap debate, but anyone have any long term reviews of the twin/tri channel boxes?, any issues with the car?.

The car id be putting it on is a year old so everything in pretty good shape. Im looking at the tri channel box from dtuk.
