My mom uses this with her cochlear implant and this works pretty well. It is pretty easy to install. All you need to do is to remove the cover which exposes the four holes on the top and then place it into your cochlear case/cleaner. For my model, you do not need to latch it or anything. It is simple just to put the block in and done. Once it is open, you cannot reseal it so be aware of that. It last for two months at a time. You can write the date you start using it on the actual product. Be aware that when writing on this, it is easy to smear as ink can take time to dry on this. I just use a permanent marker but it still smears. The block last for quite sometime and keeps the hearing aid dry and clean. I am pretty happy with it. It does not have any odd odor or cause any kind of irritation for use. It is easy to mark and know when to replace it if you write the date. Overall, it is a good brick to have and last for quite sometime.

It's convenient to mark the date on it with a Sharpie, to remember to replace it.
