These are nothing like lululemon's align pants. Way more like lululemon wonder under. They seem decent enough, especially for the price, but I was hoping for an align knock-off based on reviews. These do not have that buttery-soft texture whatsoever. I got a size small, usually wear a 6 in lulu, and a small seemed right. Any larger and I would have wanted a medium.

I used to love my Versa and I still do but I was on vacation 2 weeks ago and the Fitbit fell apart! Out of nowhere the glass portion came out of the holder that touches your wrist! I superglued it back in but ever since the battery sucks! It used to hold a full charge for about a week but now I have to charge it every 2-3 days. I haven't even had it for a year and it's already falling apart. Almost regretting this Versa

A good glimpse into the roots of rock and roll, and the excesses of the culture. Rock n' rollers are egotistical by nature, but in spite of that, it's still an interesting read. I look forward to Stephen Stills' autobiography to get another perspective.
