So there pretty much the same, both have issues, both cheap etc etc.
Does it make any difference by having a rear vent to a front vent??
In my flat i cannot connect the vent up permantly, so i would have to pull the unit out often to disconnect/reconnect the vent pipe.
With the front venters, i can put the pipe on, hang it out window, then remove pipe and put it away in the drum for the next time
