I am more than satisfied with this product. Used it for the first time to make a quick snack for a hungry male in the family and I was delighted with the end result. I confess to being dubious, and I was worried about burning, but the toasties turned out to be very tasty indeed. My husband was intrigued by the recipes that came with the bags, so I'll have to be even more creative and see how it works out.
I wonder if some of the problems people have depend on their toaster and not on the bags themselves. My only problem is that the bread I use is almost too tall for the toaster (a Kenwood) and the very top round bit isn't as crisp, but that's not so bad.
Love the bags!
Oh, my only moan - they didn't come clean in the dishwasher, despite putting them on the spikes as suggested, but again, they're small enough to do by hand and wipe out with a dry cloth.
