I purchased theses with the new style wand. The new ones do not work. I took three tests before trying this one and all three came out very positive with two dark lines. I tested theses today and the line is faint. I also tested with theses 5 days before my period and got a negative. The ones with the dark lines is there old version. So I believe something is not right with these. Purchase the old ones from the store.

Rampage series is known for being extremely friendly with the enthusiast: very overclockable, excellent support for multi-GPU and lots of treats. The X99 follows this tradition.
