TOL GE portable mixers and the short-lived GE-Universal portable mixers offered a set of plastic mixers for use in non-stick and plastic vessels. At the height of the Teflon rage, there seemed to be a marketing feature for the plastic beaters. Another feature of them was that they did not have a center post. It is true that they are not suitable for heavier mixing jobs, but then a stand mixer is better for heavier mixing jobs anyway while the portable mixer was often used decades ago near the range like for sauces or the famous Seven Minute Frosting.
In the early 70s, GE bought the old Universal small appliance name and used the combined labels to offer a "gift line" of small appliances with features not seen on GE small electrics. For example, GE's standard waffle iron/grill was the rectangular model. The Universal model was a large square model. The GE-Universal label was put on certain models from the Universal line to fill out the GE line. The toaster oven in this line not only offered the second rack enabling it to cook two TV dinners at once, the door was almond porcelain instead of chrome.
GE portable mixers had long offered the single aerator mixer for making milk shakes in a drinking glass. This was included in the GE-Universal portable mixer also.
