Yup broke 2 here too.. I replaced the back 3 bricks with the hard ceramic bricks that I bought at TSC for $3.00 each.. Stove runs same as before and those bricks are MUCH harder and heavier than the pumice bricks..I have learned that the hard way, i have replaced 2 of my rear firebricks due to hitting them too hard during loading... i have since lightend up a little....
