I picked this up because hearing aids collect a surprising amount of wax, dust and general pocket fluff, and regular cleaning really does make a difference.
The kit includes a selection of small brushes, picks and cleaning tools designed to get into the awkward little areas around the microphone ports, tubing and moulds. None of it is particularly glamorous, but it is useful.
The main thing I liked was how easy it was to keep everything together. Rather than hunting around for a random brush or tissue, I could just open the kit and get on with it. The tools are small enough to reach the areas that need attention without feeling too aggressive.
Build quality is fine rather than amazing. A couple of the smaller tools feel like they would not enjoy being thrown around in a bag for years, but for the price I would not expect anything more substantial.
If you wear hearing aids every day, this is the sort of boring little product that ends up being surprisingly useful. It is not exciting, but it does make routine maintenance quicker and easier.
