Shiri Dori: "I have the dk-gray colored one (I guess this is the set number)"
David Gregory: "I know I can't be the only person who has one of these. (Maybe I'm just the only one who bought it by itself as set 5008.)"
Ronald Plasmeijer: "No David, You're not the only one anymore (sets 630, 821 and 9892 are also brick separators). By the way, the separator works better than I had expected."
Michael Kohan: "This is the Dark Gray one, right?"
J.P. Manalo: "Makes light work of bricks tightly bound together... This is essential kit for all LEGO builders!"
Shaun Griffith: "very useful"
