We use these shower heads now for a few years - when my partner runs for several years without problems - for me the LED effect is now already at the 2nd shower head (or ists of 3) no longer functional. Often also drops the water pressure, this can be resolve by unscrewing the showerhead once and the filter cleans - created here with me at least often deposits of limestone and how it appears to solve the shower hoses with the time also something on. This approach helps but not always continue - because the shower head already no longer allowed to revive in me, I saw him just once dismantled - unfortunately all the electronics is encapsulated so that it does not ran (I'm sawing times now - ) - I suspect that the deposits (lime) in spite of filters in the "turbine area" come and lead the power generation is paralyzed. Alternatively, of course also apply rust - what I hope to find out in more detail with the sawing. Therefore the recommendation this showerheads only budget - otherwise the light effect is in the shower of course great but unfortunately not permanent
