Review title: Lemon Product review: We bought a Panasonic PV-DM2791, and we finally arranged to exchange for a different model. The worst thing about the TV is the VCR. From the very beginning, it didn't want to accept videotapes. At least 70% of the time, the tapes would "catch," and the VCR would spit them back out. When we finally got the tape into the VCR, it occasionally didn't record properly. It was very loud rewinding and fast-forwarding. Then there was the DVD player, which didn't seem to handle the sound on the DVDs very well. Half the time, we'd have to turn the volume all the way up to the max in order to hear the dialogue. We tried adjusting all the audio settings, but nothing helped.In short, steer clear of this one... The model we exchanged it for is a Panasonic PV-DM2792, and so far, it's 100% better (not to mention less expensive!).

Review title: it is not, in fact, for most "focused beginners" Product review: First I want to clarify that if you're actually a serious experienced wine maker and want to learn all the ins and outs of perfecting the wines you hand crushed from your private orchard then this is in fact a good book. My beef is that it claims to be for "focused beginners" and it is way too advanced for that.I was already quite familiar with the similar process of beer brewing so I had a leg up on most people but I still had to read through advanced processes and a sea of chemical terminology hoping they'd be defined and make sense later.What makes this book poor for newcomers is that it tends to dive straight into specifics without taking a step back and explaining basics like what is going on or why.What you can expect from this book is more of a reference manual of tips and tricks for perfecting your processes - not book that broadens your general understanding or appreciation of wine.

Review title: Dissappointing Product review: After reading a lot about Invicta watches this was a let down.Could not read the time or get the crown out to adjust the time.Maybe one of their other watches will be better.
