After the machine had been installed, I read the manual.  THen I learned that we should use some inflexible conduit between the dryer and vent. I wish this would have been listed in the description of dryer and what is needed. Our old dryer was 13 years old and used the aluminum foil flexible tubing. The installer said nothing to us. If we would have know, we would have had the right equipment ready.  Other than that, the machine is fine, but takes some adjustment with all electric selections instead of the old school dials.
