Screwzall - 2 thumbs up.
Utilikey - never could figure out how to use it without removing part of my anatomy.
Sebertech M2 - Clasp on keyring is too loose, mine kept coming off. I would go to use it and end up finding it in the car seat or somewhere like that. Otherwise I loved it.
Batonlite - very solid light, but the N cell batteries are more expensive and shorter lived than I like. I am going to sell or trade mine if I get around to it. It has been played with and left on by my daughter once too often.
Micra - Great litle tool for the price.
Space Pen - Very solid and reliable, but does not handle being laundered as well as I wish it had.... Just need to get a refill. It still writes nicely once wiped off, but blobs up when left alone for a while.
Arc AAA - Batteries are so much more convenient than the Photons'. Still, I would not be without a Photon or 2. More people have a congenital fear of that dark than a fear of not being able to cut something, however misguided that may be.
