Oil is best for making these; butter just won’t cut it. If you’ve the time to make clarified butter, it works well here. For those of us that haven’t the time to do so for a batch of waffles, feel free to use any neutral-tasting oil. I used sunflower oil, but vegetable, canola, etc. would work well too. For a bit of flavor, coconut oil is a great option.
The instructions say to warm up the waffle iron on heat setting 7, but there is no heat setting 7. The waffle iron has a knob on top numbered 1 through 6. I can't actually rotate the knob to numbers 5 and 6 though; the knob is physically stopped from rotating at 4. When I rotate the knob the other direction, I can rotate past 1 almost a full 360 degrees (stopping just before I reach 6 from the opposite side). The iron seems to heat up as soon as it's plugged in regardless of how the knob is rotated, so as far as I can tell there is no "off" setting even if I've rotated the knob to well below 1. Since I can't tell how the knob actually maps to heat settings (if the knob even does anything at all) I'm afraid to even try actually poring waffle batter onto the thing..

We considered looking at dual-purpose waffle makers with interchangeable plates such as the T-fal EZ Clean Sandwich and Waffle Maker (SW6100) but ultimately passed. Appliances that try to excel at two disparate tasks often fail at one, and from reading the reviews, it seems clear that this T-fal model—which is now discontinued—might make great sandwiches but fails to make excellent waffles.

For the second round of waffle testing, we used Stella’s overnight yeasted waffle batter. Although this batter also relies on steam to power the rise, the fermentation by the yeast fills the batter with air bubbles even before the creation of steam, so it gets a one-two punch of leavening. This batter was thicker than the buttermilk batter due to the air bubbles it contained, which meant there was no difference between waffles made in a flip waffle maker and those made in a non-flip unit. The same irons that performed poorly due to inadequate heating in the previous test fell short here as well, but with less dramatic results, because steam isn’t the only leavening agent in this batter.
The removable waffle grids are dishwasher safe. To clean the drip tray, rinse off excess overflowed batter with hot water. For easy cleanup and storage, wipe down the exterior with a damp, soapy cloth and fold the handle. Do not use steel wool, scouring pads, abrasive cleansers or sharp or pointed objects on any part, as this will tarnish the steel exterior.

When the temperature exceeds the desired setting, the strip "warps" and breaks the contact causing the resistance coils to cool. Because the iron is not being heated, the temperature falls and consequently the bimetallic strip "un-warps" and makes contact again, causing the coils to re-heat the iron. In this way, a continuous temperature is maintained in the cooking irons.
That said, quite a few users say that this waffle maker isn't as sturdily built as previous versions of the same model, and that if you don't get the top heating plate aligned just right, it can fall off -- an injury hazard if the plate is hot. The top of the G48TD also gets very hot. Some use pliers to bend the metal clips that hold the heating plates in place, which helps them line up better -- or you can just use an oven mitt to protect your hands.
