Product review (5 stars): great, but takes getting used to
We live in a brownstone in New York City with no ventilation in our cellar for a conventional dryer.  We've had the Bosch for 2 years.  Bosch makes one of the few condensation dryers with the capacity to dry large loads.  It takes about 45-60 minutes to dry a standard load of shirts and socks.  Large bedspreads take about twice as long.  It's a lot slower the conventional dryers, but it does the job.  It is easier on fabrics because it simply pulls moisture from the chamber instead of blasting clothes with hot air.  My clothes seem to hold color better. It's expensive, but fine if you don't mind the wait.

The outlet for this dryer is not conventional.  It's not a big deal (inexpensive) to get an electrician out to switch it, but that will be a small added cost.
