very important book
Format: Kindle
If you are a victim of narcissistic abuse, It’s Not You could be a revolutionary, transformative, healing read. I just finished it and feel a deep gratitude to Ramani Durvasula, PhD for dedicating her life to sharing, as she calls it, “the story of the lion” not the hunter.

Better than canned air
I got this because I got sick or buying canned air. This will pay for itself in a short time if you use canned air often enough. Surprisingly powerful and can even blow some debris from the floor of my garage from a standing position. Different attachments for whatever your need it. Well worth it. As soon as I got it I cleaned all my electronics and was satisfied by how much dust flew out of them. Electronics can now breath again and are performing as they should and are not overheating.
