Query: Weber Performer fails to perform

I bought the Weber Performer for it's great design and for the convenience of being able to use gas to ignite the charcoal. Unfortunately, after 4 months the 'igniter system' failed so I had to light the grill with matches. I contacted Weber and they gladly sent a replacement igniter. After installing the new igniter, the grill still failed to ignite properly. I tried 3 different propane tanks to see if there was something in the gas supply that created the problem but the igniter failed to work with any of them. There's a design or production flaw somewhere in the gas igniter system. If you purchase this product, plan to have a lot of matches handy.
