To maintain my original 5 year warranty I went ahead and replaced them at 300 hrs and just used the benchmark the whole time I used it.ETECs... can't say if I changed them once maybe twice in 18 years and not because I had problems just because I fugured they should not have lasted so long ... i'll lok them up just to get ready for the big shock thankfully I have a I3 .
