I agree with the other review, these chips are not for a sore mouth or tender gums. The chips are very hard and the taste is delightful if you enjoy the salt/vinegar combo. Unfortunately, every bag I received in that case was over cooked! They were very dark and only a few golden brown chips in each bag. They definitely need to improve that!

I was amazed at how good this is for canned fruit (which I normally won't touch).  In particular I adore papayas and mangos.  The fruit juice instead of syrup is also very nice.  The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch.  So far I haven't gotten a can that had any problems.  The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".

this is the second time ordering beer nuts....i can not find them anywhere in local stores.  the shipment came (6 cans per order) and 2 cans were damaged.  called amazon customer service and the next day another 6 cans appeared at my door.  the nuts are always great (unless can is damaged and nuts are stale) but the customer service was the shining star.  thank you !!  will order again
