The same here.. I've sold many,mannny ,manny bags.. It's all the matter of how they are used or abused.. You can not stick them in the HIGH votage oven for the ame amount of time as the lower votage.. Or the person that turns them for 10" min.. and takes off.. come back and ...OH a fire... Or simple do not do as directions say.. I worked in a fabric store ,lady come in was going to make potatoe bags... She had ploy batting.. tried to explain that she didn't want to use that... She tells me thats a it was batting... I tried to explain with no sucess.. So needless to say I'm sure hers catch fire... Enough said..
