I didn't know which button to press first! 3 independent settings, one for the nose with two speeds, one for the tip with two speeds and one for the circular motion again with two speeds.
Not really into the circular motion but the tip and the nose are very good even on low setting, put the nose onto full and fly away.
The only downside is the nose is a little noisy on full setting, so if the window cleaner arrives to clean the windows while you are playing, he will know exactly what your doing.
Another excellent feature is the removable battery holder from the shaft, excellent for storage too.
