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

I bought this Intex bed for my son. He is renting an apartment while waiting for a room assignment in a dorm.The bed, although still inflates, now has a bulge in the middle, so he falls off the bed. Even though we tried deflating and inflating the same, the problem is still there.

Ex Output:

Negative
