Product review (2 stars): Frigidaire Washer/Dryer stack (no center agitator)
Purchased this item brand new from Lowe's, end of January 2013.  This is my first washer/dryer combo with no center wash agitator.

When the machine is running properly, it's fantastic.  The wash cycle is significantly quieter than other machines I've used.  The knob selections leave you with very limited options as far as being able to influence the actual wash duration.  I've noticed that the "normal" wash cycle typically takes up to an hour, which is significantly longer than other machines I've used.

The spin cycle on this machine is another story... It may very well be that I have a faulty machine, but when doing larger, heavier loads (i.e. towels, blankets) the machine gets extremely finicky.  Sometimes it will run smoothly, but the majority of the time, it makes horrific clanging noises as if the wash bin is loose and thrashing around inside the machine, and the entire unit shakes and rattles wildly.  Doing "normal" loads (shirts, pants etc.), I can load the machine to 80% capacity and it usually runs okay.  But with heavier loads, if it's not under 50% capacity, the machine goes berserk.

I even had an authorized repairman take a look at the machine.  He opened up the front panel and examined the machine under load and could not locate the source of the clanging noise.

Another limitation of the machine are the knob selections.  For example, "rinse" and "spin" are a single selection.  You can't just run the spin cycle to wring wet clothes, you are forced to run the clothes through a rinse cycle as well.  This of course caused problems for myself and the repairman trying to trouble shoot the spin cycle because now we had to wait 10 minutes for the rinse cycle to complete...

Pausing the machine mid-cycle for any reason is also a no-no.  Pushing the button to halt machine operation (for example, if the machine is banging around during spin cycle) will pause the machine, shortly after which it "resets" the cycle.  So for example, if you pause the machine with 10 minutes remaining in the wash cycle, and you let it sit too long (3-5 minutes?), when you "resume" the wash cycle, it will just start all over again.

Regarding the lint trap itself is very small and clogs quickly.  Is this a limitation of the dryer or are my clothes just linty? :p  If the trap gets fully clogged, I would recommend clearing it and running the dryer cycle for a few more minutes or so in order to catch remaining lint.
Also, the dryer door has a spring in it which causes the door to close slowly when opened. This is extremely irritating when trying to put clothes into or take clothes out of the dryer.

PROS: Quiet operation (when it's working properly)
CONS: Noisy spin cycle (when it' not working properly), lack of options on the knob turn dials, small lint trap, dryer door automatically closes.

I will try to post a video shortly.
