The Presto PopLite Popcorn Popper is a great way to cook popcorn- if you are into eating healthier. It is a pretty easy machine to use. Just get about a half cup of popcorn, put it in the popper, set a bowl under it and plug it in. There isn't even an off/on switch. Just plug it in and within 5 minutes you'll have a huge bowl of popcorn.
The downside is that it is an air popper, which means your popcorn is going to essentially be flavorless. It requires no oil or butters to cook. I would highly, highly recommend melting some light butter and add a little parmesean cheese just to give it a little kick.
Also, this is a LOUD machine. It is fun to watch because the kernels don't come out hot and they ping everywhere in the PopLite popper, but be sure to cover your ears! If you were planning to make a late night popcorn snack, this isn't the machine for you.
However, if you want to live with a little less calories and not spend so much on popcorn (since you use bagged popcorn), this is a nifty little appliance. Recommended for anyone on a weight loss plan.
