I've also had less screwups using the regular toaster oven instead of T962. I suspect that's because T962 uses IR heaters instead of convection. I've regularly had slightly charred or even molten connectors on boards reflown with T962. The most extreme case was broken inner layer traces (on a board with black soldermask, which apparently had a bit too much moisture inside- the board layers visibly popped). An interesting side note- large LEDs don't like being reflown in IR ovens. The lens on large LEDs also works in reverse- it happily damages the bond wires by focusing incoming IR radiation to a point.
