What our tools can and can't do — stated plainly, not buried in fine print.
The short version
Speaker cleaning tools
The Water Eject, Deep Speaker Cleaner, Dust Remover and Earpiece Cleaner tools use sound to vibrate a speaker and help shift small amounts of surface water or dust. They cannot repair a speaker with genuine liquid or physical damage, and they are not a substitute for professional repair. We are not responsible for any device damage related to using these tools.
Measurement and hearing tools
The dB Meter gives an approximate, uncalibrated reading — it is not a certified sound level meter and shouldn't be used for anything requiring precise or legally meaningful measurement. The Hearing Test is an informal estimate for curiosity, not a medical or calibrated hearing assessment. If you have a real concern about your hearing, see an audiologist.
General use
- Don't charge your device while it's wet, regardless of what any tool on this site says.
- Stop any tool immediately if you hear distortion, buzzing, or anything that sounds worse than when you started.
- All tools are provided free, "as is," with no warranty of any kind.
