Product review (4 stars): A Great Addition for Those Who Suffer from Anti-dishwashing-itis
The SPT SD-2224DS countertop dishwasher is a fantastic addition to any singles or small families without a dishwasher.  Simply put, it does a great job at washing dishes... which is what (I hope) you're looking for in a dishwasher.

As a twenty-something bachelor living solo in an apartment, I sometimes suffer from "Anti-Dishwashing-itis".  It's a terrible condition really.  Thankfully, the SPT SD-2224DS has been a cure for me, and I'm no longer showing any symptoms of it.

So why is it so good?  Well, it does its job well.  It leaves dishes, glassware, silverware, plastic storage containers, and all that other stuff looking great.  While I haven't compared different detergents to see if the effectiveness varies, I've used my trusty Cascade powder detergent and rinse aid combo that I've been using for a while.  Why fix what ain't broken?

This dishwasher has a great feature set, with different settings which include normal/heavy loads, light loads, and just glasses.  It has a warning indicator for when you should refill the rinse aid, and the LED display is a great addition.  The default normal load takes just under 2 hours, and the lighter loads take about an hour and fifteen minutes.  If you're someone who operates on a tight schedule and likes certain things to be ready at certain times, you're in luck; this dishwasher has a delay start feature.  While that feature isn't important to me, I used it to test it out and it works great.

The machine is rather quiet; I have it in a position where the kitchen meets the dining area and living room area (open-concept apartment), and it doesn't disturb me at all.  The only time it really makes any noise is when it is ejecting the used water into the sink.  It also looks sharp.  I think the silver looks rather similar to stainless steel and fits right in if that's your decor choice for your kitchen; the black accent at the top is a nice touch, and it allows the contrasting white LED display to show clearly.

The dish-rack works well for the most part. It rolls out, and it has slots for your different items, as well as a tray for your utensils.  However, it is also rather prescriptive. What I mean by this is that there are a lot of slots, which has its pros and cons.  The pros being that it can hold plenty of items, but the cons are that those items tend to be more specific (e.g. these are your dinner plate slots, these are your bowl slots, etc.), so it can be difficult to figure out some oddball items like crockpots when there are so many slots sticking up.  It works, but it doesn't work as well as it could.  I also had the SPT SD-2201S dishwasher, which is an older model, but I loved it (there was nothing wrong with it, I just moved and sold it).  That model had a different dish-rack with fewer, but more large slots.  Again, pros and cons.

The only other issue I have with it is the faucet adapter isn't a perfect fit for my faucet, so it still leaks water.  It works fine, and it's likely a user error, and not an issue with the adapter itself.  It's just an annoyance.

I wish I could do half stars, because this is definitely a 4 1/2 star machine.  I think 4 stars is a bit too harsh, but 5 stars is giving it a little bit more credit when I have a slight preference for the DS-2201S.

Regardless, if you're looking for a countertop dishwasher, you won't go wrong with this machine.  SPT makes solid dishwashers, and my sink is now always empty and looking clean.
