I've only tested this twice so my review might change after a few months. Right now, everything works well. I used it to clean my fountain pens and it did the job. One of the piston filler pens had some stuck ink, I put that in again for but a longer period of time. Also added a tad more dish soap. It came out perfectly clear. I think with all the pens, the first cleaning will remove most of the ink. A second will complete the process. Top feature for me: Different time settings! Nice. Characteristics: size is perfect for my uses which is mostly small items. Quality: Satisfied so far. We'll see how it goes over time. Right now, touch screen is responsive. The cover on top was made to be easy to lift though it might be too easy and too light. Ease of use: I figured it out without reading the instructions. I recommended reading the instructions though. Price: Could be cheaper, but price is ok as long as this is durable. I used to own one that cost less than half the price and lasted me over 10 years. It was still working but I gave it away to upgrade to this one.
