Product review (5 stars): Great little dryer, but do NOT buy the bundle!
I had already purchased the Avanti Model D110-1 Dryer (after spotting it in a huge sale elsewhere), but came here to find items needed for set-up, and it was a bit of a challenge.  The dryer's exhaust pipe is a 3-inch oval, not the typical 4-inch round, so common connection kits and ducts will not work right out of the box.

If you already have typical materials on-hand, you can try stripping the wire away from the first few inches of a 4" flexible aluminum duct, so you will be able to snuggly clamp it down over the 3" pipe, but my attempt to do that was a dismal failure. (I actually had to update Thel's Complete Colorful Metaphor Compendium afterwards. (-:)  Having the right stuff from the get-go is much easier.

This Semi-Rigid Flexible Aluminum Duct...

...worked fine.  (I could not find any 3" d. aluminum duct less than 8' long, but this one trimmed to desired length easily.)

This Dryer Hood Vent...

...is the least expensive 3" model that I see here at the moment.  (It looks exactly like the one that I purchased a few weeks ago.)

And these Pro Tie 2-9/16" to 3-1/2" Hose Clamps...

...worked perfectly.

After buying the above, set-up was easy.  The little dryer works much better than I expected it to.  Max (sensible) load is ~a dozen extra-large t-shirts, with dry time ~120 minutes on the Warm setting.  DO be sure to clean the lint traps after every load.  It's a bit of a hassle, but worth it.  I peel off the main layer of lint by hand, then grab a little hand vac to suck the rest off quickly.

After a dozen laundry loads, I am very pleased and would not hesitate to order the same Avanti model again whenever it needs to be replaced.  (If any problems develop, I'll leap back in and add the info.)
