I haven't noticed any condensation in the tube since using this specific one with the System One unit. Not really much other choices when it comes to purchasing replacement tubes so I can't compare since this is my first unit with the heated tube feature.

Wash it before the first use (as suggested by the manufacturer), otherwise you are going to get the chemical smell.
