Q: Excellent product. I was having difficulty hearing and also getting a comfottable fit with the included ear hook that came with my Jabra JX-10 Series II Bluetooth headset. I removed the hook and attached one of the 6 gels that came in the pack to the headset and found that the volume increased 40% and I was able to achieve a comfortable fit. The headset is small enough and light enough that the gel holds the headset in the ear. I was about to give up on this headset (and all earhook type Bluetooth headsets) prior to getting the gels. If you are looking for a comfortable (and econimical) alternative for earhook type headsets, I strongly recommend that you give these a try. They are well worth the price.

Q: Can anyone who watches this movie ever erase from their mind the scene where Crawford finds out Palance and Grahame are plotting to kill her and goes stark, raving mad? It an Olympian display of overacting that has never been equalled: Crawford pulls at her hair, wildly darts her unfocused, bulging eyes, clamps her ears shut, pulls tight her grimacing mouth. A lunatic chimpanzee receiving electroshock couldn't do justice to Crawford's facial contortions here. I guess the reason that Crawford is such a fascinating screen presence to fans and nonfans alike is that she's a relentless masochist. In movie after movie, no matter what terrible fate befalls her, no matter how many times she is betrayed, it's nothing compared to the mental punishments she visits upon herself. The movie itself is serviceable but fairly ludicrous; there are glaring plot holes almost never seen in true film noir. The entire switched-identities ending is just about as bizarre as Crawford's performance.

A: Negative

Q: What is happening here. First, a sub-par greatest hits album and then this sad best of the box. I love Nirvana but Courtney Love is really tampering with Kurt Cobains catalogue. The greatest hits should of had breed, polly, and verse chorus verse. Back to the box set now.This best of the box isn't even the best of!

Negative
