Product review (2 stars): False advertisement, sound is 69dba on low.
False advertising by zline. I bought the 617-30 over cabinet range based on advertised low noise..."47 dba". On the lowest setting, its definitely alot louder than advertised. I did a sound test with my smartphone and got 69 dba on low.
 If I knew it was this loud, i would have bought the proline with the lighted buttons instead.
