Query: Good When It Works....

I've had this Air Purifier for less than 9 months and have only used it for about 6 months. About 2 months into the operation, it began to make a grinding noise as it was oscillating. So, I turned that function off at night to be able to sleep. Now the oscillating has completely stopped.I called customer relations for Kaz, Inc., as the booklet said to do, and found out that the only way to get this repaired or to receive a new one is to pay for the postage to send it back to them. Then, I have to send a $10 check to pay for their handling, packaging, and shipping charges. Seems like an expensive 5 year warranty! What if it were to happen again? I have a Holmes unit and it stopped running altogether. No problem, they sent out a new one free of charge. This will be the last Honeywell product that I will purchase!!!!!
