input with options: Title: NOT a good guide to telecom Review: I would not recommend this book to either to a beginner or to someone trying to learn more about the subject. Unfortunately the books has several major problems: 1. It does not explain fundamentals that a beginner would need to understand. 2. When it does try to go a little deeper into a subject, the explanations are so "lite" they provide very little understanding. 3. There are many errors. Is this product review negative?

input with options: Title: Just what I wanted Review: I went back and forth on which model to buy, 405 or 305, and fortunately, I didn't have to make the choice because the 305 was given to me last Christmas. I have used it for running and cycling and I really love it. I am a guy and the thing is still a bit clunky (which is why I rated it a 4 star), but other than that I really like it. Just wanted to give my 2 cents worth since I always try to scan reviews before I buy.-Great battery life-Easy to use-tracks my HR and distances-Easy computer interfaceOnly 1 issue with the interface is if you have the watch in the wrong mode (say running mode, instead of cycling) you can't go back and change that. No biggie, but it makes your calories burned look way out of whack (30 mile run in 2 hours with 2,600 calories burned- I wish).I am very satisfied with the watch and would have been happy if I purchased it myself.

input with options: Title: a step backwards for Delonghi Review: Definitely not as good as my old unit..takes too long to heat up, directions say 15 min to 1/2 hr. Filter holder is so hard to turn into place it takes one hand holding unit securely and one on the filter holder. Definitely would not recommend. Is this product review negative?

input with options: Title: The greatest opera recording ever made! Review: This recording of Tosca not only is the best Tosca around (And the bestselling) but the most perfect opera recording ever made. All the critics mention it as the best ever. The cast has never been equalled or even surpassed, the conducting blows all the more "famous" conductors out of the water. A landmark, a treasure! Callas' Tosca belongs in every opera collection!
