Product review (1 stars): 2 were burned out with blackened glass when received, other two failed within a month.
Ordered twice within past year. Tried a total of 4 with two received already blown with blackened glass. 1 burned out the first day & 1 burned out within one month.  It appeared they all had been used before shipped.  I gave up and now turn on the kitchen light when I use the water or ice.
