As described above, after 2 days, the first Nitro was defective, was exchanged. About 1 week, the whistle was also reasonably ok, then went nothing at once. Cleaned pipe, contacts checked batteries loaded, everything is ok, but the whistle evaporation no longer piece. First put in the corner, had to Liquid taste eh tired. Well I thought today, just try again, everything clean again, looked up, batteries etc Loading ... Nothing, the whistle just does nothing.
The pipe looks good, but can pure nothing, just waste, hazardous waste!
