Roomba 500 series:
Don’t buy it America, Cheap Chinese Junk, second time broken under warranty - parts are on NATIONAL BACK ORDER. Do we have a problem with the brushes??? 
Although credit should be given, to the fine customer service department, helpful, courteous, but unless you can to afford to buy 2 of them - one for backup - stay away.

Lowes Jenn Air Grill: Don’t Buy it America
$1,100.00 - and it broke on day 2, broke again on day 20, broke again on day 68 and continues to break to this day. I had the burners go bad after only 3 years of use - called the manufacturer - by the way is not Jenn Air, or Lowes, but a cheap Chinese junk maker named -Nexgrill - . Jenn Air didn't even know what I was talking about, after thorough investigation I found out that Jenn Air sold their name (license) to Nexgrill - Shame on Jenn Air - That is the sole reason I was foolish enough to purchase this without the proper research!  
Jenn Air - let it be known - you have lost my buissnes forever!
Back to the story - onmce I found out who actually serviced it -t hey said sure, no problem, guaranteed for life, but the shipping and Handling will be $142.00 !!!
DONT BUY IT AMERICA!
