When I began to use our new K-Supreme Plus, we were continually concerned about the lights in the house blinking when a cup was brewing. No matter what setting of strength and/or temperature, the lights blinked. I hired an electrician to check the circuits during operation and could not determine why the coffee make caused the lights to pulsate dim to bright. Other appliances of much greater wattage did not affect the lights. Having brought this to the attention of Keurig, the coffee maker was replaced since it was still under warranty. As things would have it, the new, replacement coffee maker does the same but not on all settings of strength and temperature. Therefore, we are limited as to which features of the coffee maker as advertised and promoted that we can use. A customer looking to purchase a K-Supreme Plus might want to rethink their options.
We had a problem with ours and with a very quick call to the manufacturer we were sent a brand new one. Great customer service and the employee working with me was extremely nice.
When my Kuereg stopped working I called requesting help and information and found that the service was excellent. A new part was sent in a very timely manner and when that did not solve the problem a new Kuereg was sent as a replacement.
I love the coffee maker, but the replacement was somewhat difficult, some my problem with understanding everything I needed ie photos of to show what product looked like, serial numbers, and copy of receipt, so it required my calling several times and talking to different representatives and some time for review before replacement was sent.
