I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.
Negative

Last year I found this book and once I opened it I could not put it down. Bugliosi is excellent at bringing the details to life on the page. Not only do we get a first hand account of the trial, but he also explains much of the legal process in very clear and understandable terminology. I am now a fan of his work and will be reading everything I can of his.
Positive

Very compact, well made, helps me level the camera when I set it on sloped surfaces and it stays in place due to the rubber feet. For the price and size it's a great alternative.

Positive
