I am totally embarrassed and apologize. I ordered an E-trac cover when I got my machine and I received a cover a few days after the ET as I ordered it when O ordered the ET, but the dealer didn't have it in stock, then. I thought it looked different from the cover that I have for the SE and I was operating from memory. Maybe not a good idea when you get older. I just went out into the shop and checked and I have two identical covers, both SE covers. Sorry! I have used the cover successfully a few times and it fits fine. You do have to kind of stretch it over the ET but being tighter, the clear plastic fits tighter against the LCD panel and there is less light reflecting and blocking what's on the screen. I may have to talk with the person from whom I purchased this as I clearly stated I wanted the cover for the ET. That was very early in their release, I got one of five that a sponsor here had, and maybe that person also thought it was the correct cover for the ET. If I had to lay money on it, I would say we both got fooled and the mistake(s) will be corrected for both of us. Again...sorry for that bad info. Jim
