I have two of them and I have dropped both of them several times, usually with no problem except perhaps the battery cover coming off and my having to put the batteries back in. On a couple of other occasions, one of my Intellitouch tuners came apart when I dropped it; again, all I had to do was re-assemble it. Finally, I dropped one and it came apart so that I have to hold it together with a rubber band (which crosses the face where the note readings appear)--or I could probably use electrical tape.
Nevertheless, I have yet to have to replace a battery or the tuners themselves.
