About a year ago I purchased a new Woodstock Progress Hybrid stove, but only had it installed in May of this year. Just for the heck of it I contacted Woodstock to see if there were any issues I should be aware of before I fire her up this fall. Woodstock told me that there had been several significant improvements made to the catalytic combustor and the cook top and that they would ship me out replacements immediately at no cost to me. Now in my book, that is great customer service and represents a company that stands behind its products. WELL DONE WOODSTOCK
