The iSonic D2840 is a compact countertop ultrasonic cleaner with a 0.75 L oval stainless steel tank and a 42,000 Hz transducer. It runs five preset cycles from 90 to 480 seconds on a digital panel, and the wider oval tank fits oversized sunglasses and watches that many small round-tank cleaners cannot. It ships with a plastic basket, a watch stand and a sample of iSonic cleaning concentrate. Compared with basic dial-timer cleaners it offers more cycle choice and a larger opening, but it has no heating element and no sweep frequency, features found on pricier units.

The iSonic D2840 Digital Ultrasonic Cleaner is a compact countertop unit for cleaning jewelry, eyeglasses, watches, and large fashion sunglasses. It uses ultrasonic sound waves at 42,000 Hz to create microscopic cavitation bubbles in water. These bubbles dislodge dirt, oils, and residue from detailed settings, hinges, narrow crevices, and other hard-to-reach areas.
It has room for larger items such as oversized sunglasses. The polished stainless steel construction is durable and easy to maintain.
A digital control panel offers five preset cleaning cycles: 90, 180, 280, 380, and 480 seconds. The housing has a silver and gray finish with chrome-plated trim. A plastic basket and a watch stand are included, along with a sample of iSonic Ultrasonic Cleaning Solution Concentrate.
