[EX Q]: I bought this set for my husband and brother for Christmas last year then we ended up buying a different set for the movie cash for the new movie. I went to sell this set at used movie retailer and they informed me it was from overseas and possibly a bootleg. WATCH OUT!!!!!!!!
[EX A]: Negative

[EX Q]: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.
[EX A]: Negative

[EX Q]: Well, this is one of those "you get what you pay for" kind of reviews. Didn't pay much, didn't expect much, but basically functional would've been nice. The generator came broken (probably a miswire internally). Yep, I checked the outs with a meter... and if I finagled the probe inside and touched the right spot, I got voltage. Just not externally. Too much trouble to return it and convinced my 10-year old to go with a real light powered by batteries.
[EX A]:
Negative
