Ordered on Feb 14 off Ebay. Citipower X3,X5 and X7. X5 has a pocket clip. The other two have lanyards. Led is nicely centered in X3 and X7 but X5 is off center. Doesn't seem to affect the beam much. All 3 have 5 modes with memory and two blinkys. X7 is by far the brightest and has the most throw. The X3 and X5 are very similar in size and brightness but the X3 has a little brighter hot spot. All three have a very cool white beam.
All seem to be useful lights and well worth the money. Less than $12 for the X3 and X5 and $20 for the X7 shipped.
When comparing the X7 to my new Romisen T601, the Romisen is brighter and throws better. The X7 has a more useful UI and the low mode looks to be handy.
