[EX 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.
[EX A]: Positive

[EX Q]: It brought home an old classic - I can watch these guys over and over again.

[EX Q]: I read up on belly-wrapping after my c-section and bought a couple compression tank-tops from Wal-Mart, which worked nicely. I wanted something without straps and something with more compression and purchased the Squeem Perfect Waist on Amazon after reading rave reviews. When I received it and tried it on, it felt disgusting on my skin. It was uncomfortable and totally noticeable (even without a super-tight or thin shirt on), especially when I sat down. The seams and the boning are all very noticeable, and the rubber makes clothes catch and stick in a really weird way, like something would stick to you if you were really sweaty. I have wore corsets for years, and this is by far the grossest feeling and least comfortable thing I have ever put on my body. I returned it immediately.
