Q: 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.

A: Negative

Q: I purchased this as a replacement for an old roll up tatami mat that I purhased at least twenty years ago. These are perfect for taking to the beach but couldn't find them local now. The tatami is woven tightly so that it keeps the sand off. Saw this and looked like a good idea.These are really three separate tatami mats, each about 11" wide by about 6' in length, joined by a blue canvas strip that runs the full length (top to bottom). It is colorful and handy, folding up in to object about the size of a large book with handles.Problem I ran into was that the strip joining two of the panels ripped apart first time I took it to the beach, rendering it useless for its intended purpose. Perhaps mine was just a bad sample but at $10 a throw, I will be asking for a refund.

A:
Negative
