Q: [...]I would not recommend this book. Russell does make some remarkable findings, however, his theology is corrupt and he is a party to a cult.

A: Negative

Q: I've reviewed a couple of other Waechtersbach items, and I'm quite happy with these as well! I have only two minor complaints. First, on these, the glaze seems to be scratching (utensils?) more than the other Waechtersbach products I have...my plates and cereal bowls aren't doing that. Second, all four of them had a funny little bump on the outside rim...it looked identical on all four. Maybe a slight manufacturing defect? The glaze is slightly darker around the bump, so you can see it, though it's not overly obvious. But overall I love them - they're great for soups and pasta (spaghetti especially). They're holding up quite well in the dishwasher, too - no chips or cracks, despite how they sort of lean against one another. Very pleased!

A: Positive

Q: Air mattress: Looks good, works but requires frequent running of pump. Appears to lose air through the built-in pump. Should have returned the mattress but need the bed for visitor. Probable would not buy with built-in pump in future.

A:
Negative
