I already have one of these!  Have used it for years and intend on using this one for years, too.  Only purchased a second one to keep at our place in Florida!  Love Whirley Pop!!

Pros: Lightweight (great for older hands and wrists!), easy to handle, and does a fabulous job of popping popcorn!
Cons: They are a bit of a pain to keep really clean because the oil builds up.  But, it can be done!!
