Well, from my personal experience, i'd say the twist tool is very tricky to get positioned right. I had it working 3-4 times; then closed the lid, only to find it had slipped. Ended up popping the case screws and getting out the old duct tape to cover the sensor. The tissue/tape method is very easy and has clear instructions on this forum. Save a couple bucks and don't have the fuss. For those worried about the warranty, well it's been my experience that most times the company won't cover the repair anyway. But to each thier own; be forewarned about the difficultly of using the twist tool.
