How much cotton candy can I make in one batch, and how long does it take?
One scoop at a time, which one owner puts at about a tablespoon of sugar and the most the head will take. Nostalgia says you will have cotton candy within a few short minutes of warming up, and owners broadly agree once the machine is properly hot: one had floss spinning in about a minute after a full warm-up. Speed across a whole session is the common complaint, though. A grandparent estimates 4 or 5 minutes per cone, and an owner who made six batches found they were eaten faster than they could make them. For a group, make some ahead.
Can I use hard candy instead of flossing sugar?
Yes. Nostalgia says the extractor head takes traditional flossing sugar or your favourite hard candies, and owners report both work well. Whole candies will spin, but one owner gets smoother, faster floss by crushing them and mixing in a little ordinary sugar. Avoid dropping in big lumps, including hardened leftovers from a previous batch: one owner found they unbalanced the spinning head. Nostalgia pairs the machine with its own flossing sugar and hard candy kits, and no sugar comes in the box.
Is this machine sturdy, or does it wobble during use?
It depends partly on your unit and your counter. Nostalgia fits suction cup feet to hold it in place, and the machine is light, 3.54 pounds, which is why those feet matter. One grandparent still found it vibrated enough to need a second person holding it, and the shaking could loosen the plastic bowl; rubberised shelf liner helped a little. Another owner's machine arrived with no feet and needed rubber feet fitted before it stayed put. Check the feet as soon as it arrives, and run it on a clean, flat, empty counter.
How easy is it to clean afterward?
Easy, with one awkward step. Nostalgia designed the unit to come apart for cleaning, and owners soak the sugary parts in hot water for a short while, which dissolves the residue with no scrubbing. The awkward step is the spinning head: one grandparent found it fits very tightly and is harder still to remove once cooled sugar has set on it, so let it cool and have an adult do it. Keep the tiny outlet the floss comes out of clear; one owner who cleans it after every use, as the manual describes, has had no problems.
Is it safe for children to use?
With an adult nearby, yes. One owner points out that Nostalgia says it is not a toy and includes safety instructions, and the head gets hot. A grandparent's 11-year-old could put it together and use it after reading the directions, but learned to start the cone inside the bowl and then lift it above, because dipping the cone straight down made it easy to bump the hot head and melt the candy. An owner who had read warnings about the machine overheating says it is very safe if you follow the directions. Leave removing the head for cleaning to an adult.
Is this worth buying for the retro look, or does it actually perform?
Both, within limits. The red retro shell and jukebox-and-muscle-car styling are for looks, not performance. Buyers are positive about how much fun it is, how the cotton candy tastes and its size, which means people who use it as intended tend to like the results, but they rate it poorly on speed and durability. Buy it for the retro look and small-batch home fun, but go in expecting a slow, light-duty machine rather than a guaranteed daily performer.
