I haven't seen them but they are not a good diet snack, no protien or fat, they probably won't satisfy your hungar pangs for long
A good diet snack is a balanced one, including some protien.
I also don't see the point in paying to have fruit pre-prepared and put in a bowl, its not that much hassle to grab and apple or peel an orange/apple.
Also they may only be 60 calories a bowl but the potion is fairly small, and for the same weight in strawberries I would save just under 30 cals.
Never be fooled by diet or health foods, read the nutrional informaiton label first.
