Product review (4 stars): Good, but a couple issue
Pros:
1. Huge!  We can wash and dry a king comforter with ease and very large loads of clothes.  We really haven't taken advantage of the side-kick other than to just try it out, (purchasing it more as a novelty) but it works fine.  If you want to save a little, don't get the sidekick.
2. The pair was delivered without damage and dropped into my garage for inspection.  I hired a local handyman to hook the things up, there was no way I would have been able to get them into the laundry room by myself.  We spent $100 on him, and with the savings, I didn't have a problem with that.

Cons:
1.  It comes with the Y adapters for the sidekick but you will still have to buy other hoses and the electrical connection for the dryer.  The provided hoses are relatively cheap as you would expect.
2.  A big negative for us is that the doors aren't interchangeable for which way they open, we had to position the dryer on the right side or they would have opened back to back.  (I think our setup is backward with the dryer vent on the left and washer hookups on the right)  so check what yours may be- you want the dryer vent on the right). This caused us to run the dryer vent behind the washer and out the vent.  We keep getting a D-80 code which is for a clogged vent, but it has been professionally cleaned, we believe the is sensing the extra tubing and 90 degree turns we had to make to accommodate the doors.  The extra vent turns also cause heavy wet items to take a few cycles to dry.

Lastly, the seller was nothing wonderful.  They called a couple days before the anticipated delivery and said it wasn't in stock, we could get another color, I said no.  We were offered the next years model as compensation, fine.  The second delivery day came and went and I called customer service to ask where the pair was and why the tracking number wouldn't work, uuuuuh we don't have any in stock.  A few more weeks go by and bing, a call from the freight company to set up delivery.  So, aggravating, but worth a few extra days for the savings.

All in all.  The washer and dryer are decent and large.  The sidekick is meh.  The seller is average, or worse, but worth the savings over the big box stores.  Don't buy if your dryer vent is on the left side.
