[EX Q]: I have not yet received the DVD . I have not yet received the DVD, and I contacted the customer's service last month. They sent me a new shipment, but I am still waiting for it
[EX A]: NEG

[EX Q]: Poor video quality . I purchased this product to benefit from dvd technology.  The reviews on the website led me to believe that this product was somehow updated, or upgraded for use with dvd technology.  Last winter, I ordered the video, which is is like a pirated version, with very low resolution.  If I could, I would return the two dvds I purchased.  I feel ripped off and stuck with an inferior product.    I love callanetics content.  Amazon should be urging this company to provide new material.  It's no help to see a sticker on the dvd I purchased announcing new products in Dec. 2006, which is when I purchased two inferior Callanetics dvds
[EX A]: NEG

[EX Q]: The Best Workout - EVER! . I love the Firm workout tapes.  I used them before my wedding trying to get fit.  They really do work in 10 workouts or less!  Once I had my baby, I started using them again, and with no doubt, they worked!  This is the only workout that I really enjoy, I don't have to work out for 2 or 3 hours to get the effective results.  I think about this workout when I'm not doing it, and I really enjoy it!  I recommend this and any other tapes from the series to anyone.  Trust me, you just put in the work, and the workouts do the rest!  They're not easy, but they are effective
[EX A]:
POS
