RIGHT-SIZED FOR TWO

6 place settings — top of the countertop class, where the tank-fed units stop at 2-4.

✓

CLEANING

Cleared about 96% of test stains in just 100 minutes — Reviewed calls that comparable to full-size dishwashers.

✓

CYCLE CHOICE

8 wash cycles (Heavy, Normal, Baby Care, ECO, Glass, Speed, Rinse, Mini Party) — rare at this price point.

✓

NO FLOOR SPACE

Sits on the counter and connects to any standard faucet with the included quick-connect adapter.

✓

RUNNING COST

Energy Star certified at just 3.1 gallons per normal cycle; the stainless interior is quieter than plastic.

✓

■ The catch — co-equal billing, always

You can't order it on Amazon right now. It's still in production but out of stock there, so you're buying from Home Depot, Walmart or danby.com. And it repriced upward: about $425 today against roughly $357 before.

Dealbreaker? Runner-up №1 is the Amazon-today answer at $300 ↓

Runners-up — if your needs differ

Ordering on Amazon mattersmore than 8 wash cycles

Traps — this verdict avoids

Trap 01

Phantom place settings

Countertop units hold 2-6 place settings, not the 8-12 a full-size rolling portable takes — and they clean significantly worse on baked-on food. Decide which category you're buying before you compare prices.

Trap 02

The faucet decides

Rolling portables need a kitchen faucet with a threaded aerator for the quick-connect adapter, and pull-down or pull-out spray faucets typically need a separate adapter. Check your faucet first — tank-fed countertop units are the only hookup-free way out.

Trap 03

Portable, built-in money

Full-size rolling portables run $800-1,050 — comparable to many built-in dishwashers, which out-clean them in every metric. Countertop units start at $200-350. If you can install a built-in, install it.
