Q: I have had the charger for more than two years. It charges AA batteries just fine, but has a huge problem securing smaller AAA batteries. To charge the smaller batteries you need to flip down the little button at the positive end. In the beginning one of the four AAA batteries would pop up, and now three out of the four won't hold. The problem is the flip mechanism became loose, and any horizontal pressure would push the buttons back up. What I have to do now is using duct tape and a segment of crayon, apply the crayon on the buttons, and wrap the tape around. You know how painful that is.

A: Negative

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.

A: Positive

Q: I love all the Sister Fidelma stories, and these short story anthologies are particularly interesting. I'm building quite a collection on my Kindle.
