Generally satisfied.
1. The size is idea fit my toothbrush. I am using Oral-B Pulsar Vibrating Bristles Toothbrush. For the case I purchased earlier, has 1mm smaller, that case can not be closed.<br /><br />2. I am not sure it is really help to kill the germ. But it is  a good case protect to be contiguous.<br /><br />3. So far not having battery issue.<br /><br />4. If the inside gave a bit free room for an 10g tooth paste , it will be perfect.
