Torrey Pines SC25 Orbital Mixing Chilling Heating Plate - Powers On I don't have a power adapter for this, but I used a power adapter that we use for testing, and it does power on and advances through different screens. I played around with the up and down arrow buttons, and I can get the temperature settings to change on the screen, but I don't feel any temperature change on the platform. I wasn't able to figure out how to change the speed setting. I don't know if it is supposed to but the platform orbits around smoothly but about every 5 seconds it has a slight pause (see video). I don't know if the issues are that this has some problems or if it is just that I haven't figured out how to operate this correctly, but I am offering AS-IS. L1-7 fdk 80327258
