I have had one for 2 1/2 years & can't imagine not having one. Does a great job & with next to no oil - it really does use only a Tbsp !!
For a family, I would recommend the larger size as you might find the regular size too small. Make sure you follow the directions especially for "drying" the moisture out of the potatoes or your fries will not be crisp. We all buy "toys" that end up in the cupboard, for me, this is not one of them. I use mine all the time & love it. Hope this helps.
