You're welcome!
I love the Travelflex because it's light and handy, but if you look at the pictures again, you'll see the Travelflex's light seems to have a violet/bluish hue compared to the Xtraflex2. I don't know if all Travelflexes/Xtraflex2's are like this, I only have mine to compare against each other
If I use the Travelflex by itself, I hardly notice the light color but when I compare it to the Xtraflex2 (I sometimes clip both lights side by side and turn one on, and the other off, back and forth
), I find myself preferring the light on the Xtraflex2 (even on one LED).
I mostly use the Xtraflex2 at night when I'm in bed. All other times though, I use the Travelflex (and bring it with me everywhere my Reader goes). If I had to choose just one, I'd go for the Travelflex
