I bought the gravity induction version, so some of my comments apply to the gravity induction feature.
I was initially confused when the item didn't turn on when I pushed the power button. Try putting a cup of coffee, tea, or soup on the heater before you push the power button. If that doesn't work make sure the heater isn't sitting on a cord or other item and is on a flat surface. This cup warmer will not turn on if there is no cup on the heating plate. Several times now the unit refused to turn on when there was a cup of coffee on the heater. In every case a power cord had worked its way under the unit, and it worked when the cord was removed. Check for that sort of thing if your warmer doesn't turn on.
You can select from a large range of temperatures. Very nice.
It seems the industry is using the term "gravity induction" for these items. This seems dishonest to me. It may be technically correct, but I have an induction stove, and associate the term induction with that type of technology. To me it implies you are getting some remarkable technology that you are not getting. When used for these devices it means it has a weight activated switch.
When you lift the cup off of the heater the lights start blinking. It does not actually turn off immediately. When you put the cup back on the device the lights will stop blinking and heating is resumed. It will turn off if the cup is removed for a long period of time. I have not found that this is a problem.
I will say that I see no purpose in the "gravity induction" feature if you can remember to turn the unit off when you are done with it; it will only be a source of problems. I don't believe it turns the heater off when you remove the cup and turns the unit on again when the cup is replaced. I believe it only turns the unit off if the cup is removed for a longer period of time. You don't really want the heater to be turned off when the cup is temporarily removed. The heater is a very low powered one. It is powered by USB after all. When the unit is first turned on you can watch the heat slowly climb up to the temperature you set.
I have found two brands of cups that work well with the Cosori beverage warmer. There are advantages and disadvantages with both.
The Cosori stainless steel cups are well made and look nice. I use coffee creamer and do not fill the cup clear to the top. The cup rim has not burned my lips. I believe these should be dishwasher safe. But the coffee cools very quickly when not on the warmer. I drink half a cup at a table with no warmer before going to a place where I have access to a warmer. So I consider this to be a problem. The Cosori will warm a cold cup of coffee however. The Cosori cup is a light cup and the unit will not turn on if there is only a little coffee in the cup. The gravity switch is on the bottom of the unit toward the back, so moving the cup toward the back of the heating plate helps a little.
The Howay cups are a flat bottomed ceramic cup with a steel plate on the bottom. Your beverage will stay warm much longer in this cup. It is made for coffee warmers. It does have a wood handle, so I wouldn't put it in the dishwasher. Because of my habits the Howay cups work better for me. These cups are heavy enough to activate the unit when there is no coffee in the cup.
Heating efficiency of these units depends on the design of the cups used. The Howay cups need a higher heater temperature than the Cosori cups to achieve the same coffee temperature. Mixing cup types means you would have to keep changing the heater temperature to achieve the beverage temperature you want. I would recommend selecting one cup type and sticking with that.
