[EX A]: Positive

[EX 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.
[EX A]: Negative

[EX Q]: We just finished with a trip to visit family and it worked great. Around 500 miles each way.It took about an hour to get it adjusted so I could get all 4 bikes on at once. After that, everything was set and I loaded 4 bikes in 10-15 minutes. I'm sure I'll get even better.The only improvement they could make would be to have two posts with more space. The middle 2 bikes fit really tight so you have to put them in just right. It was harder because my son has a BMX style bike and our daughter has a similar bike with 16" (I believe) wheels. Those fall through the mounts, but it stays in there securely anyway.My arms don't lock in the down position very easily, but I only use that for storage so I'm not worried. I'd probably buy it again, especially for the price.
[EX A]:
Positive
