The SSILD method is very effective. I think the key is that the method turns people into hypnagogic state fast, as it emphasize an easy manner instead of focusing.

I tried it last night and achieved 2 LD without failure.

Both of them were wake-initiated although the tutorial claims that DILD may occur.

However, this method did cause false awakening.

Both of my dream began with waking up in bed. Though I could quickly recognize the abnormal parts. Also, I have to mention that the pinch-nose reality check gave false result in one LD.
