What every best Washer-Dryer Combos has:
Home Depot carries as good a selection of washer-dryer combos as anyone, and searching for specific models, which can then be sorted by price or rating, is very easy to do. Many of the reviews here were originally posted at the makers' web sites, but there are some that are unique to Home Depot. Reviews are also helpfully broken down by features, energy efficiency, quality and value, and reviewers can say if they would recommend the product.
Lowe's sells pretty much the same laundry centers and washer-dryer combos as Home Depot, and they get similar ratings here -- no surprise since they, too, import reviews from the manufacturer's websites. Reviewers sort their ratings by features, value, design, quality and ease of use, and also say if they would recommend the item.
Best Buy sells fewer laundry centers and combos than Home Depot or Lowe's but is one of the few online retailers to thus far not mingle reviews from other sources with those of its own customers. However, few of the currently listed stacked units or combos has attract a significant number of reviews, and most haven't impressed the few users that have taken the time to comment.
Amazon lists a number of laundry centers and washer-dryer combos, and some get a significant number of reviews. Amazon also does not include reviews from other sites/manufacturers. Reviews here tend to be thorough and include pros and cons; many owners come back after some time to report on durability as well.
Since Sears is the only place you can buy Kenmore products, this is one of the few places you'll find user reviews of that brand. None of the brand's laundry centers seems a particular standout, however, with most models receiving only a smattering of reviews and middling scores. Sears offers laundry centers from other makers as well, but those draw heavily from the same reviews from manufacturer sites also cross-posted at Home Depot, Lowe's and elsewhere.
AJ Madison is an appliance retailer that also hosts user reviews of laundry centers and washer-dryer combos. Some products get a handful of unique reviews from AJ Madison buyers, but the majority were originally posted on other sites and are no different, or more or less helpful, than what can be seen at the sites above.
ABT sells a couple of dozen 20 laundry centers and combo units. Of these, the laundry centers show the most feedback, but again most originate at other sources such as manufacturer sites. Some unique reviews from ABT users can be found, but fewer than at sites such as Home Depot and Lowe's.
