Guess you never heard of the term "If you want it boken, give it to fire/ems"
I work on all these defibs. Ever wonder why the LP12 has a SCREEN PROTECTOR? A nice addition to the LP12, with velcro. Maybe that will tell you something. Ever wonder why the MRX has a new SCREEN PROTECTOR??? Its just cosmetic I guess. I suppose just because you havent seen one break, it means it doesnt happen? I Have repaired about 10 LP12 sceeens, even with the protector. My buddy has replaced 5 MRx screens for one county alone. I have had them stepped on, kicked, run over, attacked with a stretcher, and used as a knee rest. Even the M Series has them brake (which is covered by warranty with extreem pack). Sometimes when you dont know what your talking about, its better to be quiet.
