Just got in the EE X5 today from FT, also got in the "new" better ThorFire TG06, details in post #85. Really like the X5 - side button feels pretty good, excellent Eagle Eye finish to it, rugged SS bezel, though it has some sharp edges - gotta sand them down before putting in a pocket.
The X5 though is a long light - at 136 mm, it matches the X6R in length, longer than a X6, and lot longer than typical tube lights like the S2+ at about 120 mm. The fwd clicky works quite well - turns on the last mode selected. Modes are selected only on the side switch, and gotta use the tail switch to turn the light off. 5 modes, lo to hi, plus a variable strobe accessed on a press&hold.
On a LG HG2, measured: 2.95A tail, lumens: 1020 @start, 932 @30 secs, 8.75 kcd (218 meters).
Overall, really like it - the length is fine with me for the most part, button has a good feel and low profile, pretty good SMO beam profile - nice focused hot spot.
