We live in a coastal community and the salt air does tend to corrode the battery connections. I think this might be the second igniter kit I've installed since we bought our Weber BBQ in 2009. Not too bad! What I really appreciate is that you can find replacement parts for virtually any part that might fail and this makes the initial investment in a Weber product easy to justify.
Ordered this kit for an older Genesis grill that no longer ignited with the original button. The new one was pretty easy to install, following the directions included with the kit. Few simple tools and steps, and it was as good as new!
