Product review (5 stars): If you're on the fence, GET UP OFF OF IT. Do the thing!!
I researched and waited for three years in my home (built in 1940 so no plumbing or wiring for a built-in dishwasher) before I finally was able to purchase a countertop dishwasher and let me tell you, it was THE best decision I have ever made. I have fibromyalgia so my back and upper body strength is not at all what it used to be, but I was able to get the (rather large) box inside and up six steps on my own without too much trouble. Pulling the dishwasher out wasn't a hassle either. The exceptionally frail, however, will need some help with this. Setup wasn't difficult at all and only took a few minutes. Do be careful not to overtighten any of your lines. The fit will be snug, but you won't need to struggle with it to get it tight enough. If you're struggling, or using any tools to tighten further, you're doing it wrong.

Regular-sized dinner plates fit just fine, and I'm actually using the "cup rack" for serving utensils, spatulas, anything with long handles, and coffee mug lids. Deeper bowls need to be loaded upside down, which will cut back on how much you can put in per load, but that's fine with me, honestly. Coffee mugs need to be loaded on the bottom rack as well - they will NOT fit on the cup rack.

One review mentioned that a hand sprayer started shooting water because of a pressure build-up, but I have a hand sprayer on my sink (and it's nothing expensive or nice, just your run-of-the-mill sprayer setup) and I haven't had a single problem with it. I prepared for the possibility, but there hasn't been any problem. If you're thinking of getting this but aren't sure about having a hand sprayer, I'd recommend trying it first (just put a pot over top of the sprayer during the first operation) to see if there's a problem before you go out and try and replace your faucet to accommodate this.

I used Jet Dry Finish rinse aid and am using Cascade Platinum pods as the detergent. The manual does say these are easily accommodated, but that one should run one of the longer cycles (Normal or Heavy) as sometimes the pods can take a while to dissolve all the way. No trouble at all.

The manual also says to prewash your dishes to avoid clogging any filters, but that's mostly just for larger food particles, just like you'd do with any other dishwasher. Smaller particles, sauces, oils, beverage residue, etc are fine to leave on there and your dishes will come clean with no problem if you're using a good detergent. Be smart with what you put in there and you won't have an issue.

This unit does take up quite a bit of counter space, but it will fit on a standard-width counter without hanging over the edge. If you don't have a lot of spare counter space, you may want to find a cart to keep it on (one with casters works best) and roll the cart back and forth when you need to use the unit.

Operation is surprisingly quiet. The only time it's noisy is when the dirty water shoots into the sink, but that's to be expected, amirite?

I am INCREDIBLY happy with this dishwasher, and wish I had been able to afford/accommodate it sooner. Three years of washing dishes by hand was QUITE enough! Large dishes will still obviously be washed by hand, but that's maybe ten minutes at the sink rather than two hours to do a few days' worth of dishes. If you like doing dishes by hand, then, y'know, you do you, but if you're like me and dishes are your arch-nemesis, GET THIS THING. It is SO worth every penny to be able to put in a load and leave it for an hour or so!
