As long as you're gentle you will have no problems, there is lots of warnings in the manual about glass top stoves but I think it is more so for covering their a$$, whenever the pressure canner or cast iron(my goto pans) are near the stove I am always extra careful, and I have ran several full loads on top of it. I have often though about buying a second glass top and putting it away just in case I have a bad day =) However, when a big clamming day comes along, which usually results in 4-6 guys and some beer being drank, I always break out the propane burner, hard to crack one of them!
I should add, I thought long and hard about spending the money on the All American (think I paid a little over $300CAD), but I was buying bottled bar clams for $9 a bottle, the first year I put away near 50 bottles for myself, I paid for the canner right there and then some, not that I would have bought 50 bottles that year, but they are still worth $9 a bottle. I had lots of happy people that Christmas, who are going to be a little disappointed this Christmas
