Not same as Dohm 2013 version This 2018 version (Model M1DSUSTN) is not the same as the 2013 version (Model DOHM DS). The case designs are slightly different. 2013: 4 screws on bottom, gray foam rubber on bottom, case shell surrounding switch tapers vertically, acrylic curved Dohm branded cap top center. 2018: 2 screws on bottom with molded internal clips, 4 clear hard rubber feet on bottom, case shell surrounding switch straight up & down vertically, Dohm branded silver colored sticker top center. The main difference, and the reason I'm returning this 2018 model, is the sound. The 2018 has a slight rattle and clicking noise which I cannot sleep to. An inferior motor? An artifact of the different case design? I don't know. Measuring temperature at the bottom with a laser infrared thermometer, after running a few hours, with airflow dials constrained fully clockwise, the 2013 model measured 96.5°F; the 2018 model 110.6°F. Higher temperature could be due to absence of foam rubber on the bottom or higher internal resistance and/or friction in the fan motor.
