Rated 4 out of 5 by Dave48 This product is very quiet. It replaced the same type of bulb from home depot that gave off that high pitched ring.
Only a month old but so far it is performing well.

Rated 2 out of 5 by yehudal Durability is poor and the bulbs don't dim well.
Upon delivery, two of the six bulbs that I ordered were defective and were replaced. Now, three months later, one of them burned out (with little use). In addition, though these bulbs do dim, they will only go down to about 50% (my estimate) before flickering.
