So theres been some questions recently about the lifespan of LI heads, specifically the laser diodes in them. (radarroy's blog etc) In fact I was on the phone with Leon (blinderdude for those that didn't know) and he claimed that LI heads have repeatedly been proven to fail after 6-8 months.
I don't personally believe this since I haven't really seen that many threads about people having this problem. Plus LIUSA have said they are now warrantying the diodes for a lifetime.
But **** lets take a poll, whose had an LI head fail on them??
