Query: Takes a while to get cold again after use.

The first one of these I bought was defective - I would never shut off the cooling cycle and the "cold" light would never come on. Returned (they would not issue a refund), so I had to get another one. It works OK, but can take up to 3 hours to get to the "cold" setting and stop the cooling cycle. Somewhat noisy when cooling. I might recommend looking for another unit before buying this one.
