[Q]: After a year of this product working fine, our internet provider recommended we do a hard reset of this device to improve the connection between this router and our modem. That's when the problems began. Netgear spent over 30 minutes on the phone with us, found the issue and then wanted $139 for further support, more than we paid for the router initially. Escalating to a supervisor he offered a lower price but no other options other than a troubleshooting article we could have found ourselves (if we had internet connection). We have lost a day of work, still don't have internet, Netgear doesn't care in the least.
[A]: negative

[Q]: This is a life saving book for gastric stage one and two patients. This book is the ideal book for somebody who is thinking about the gastric sleeve technique. Well ordered it sets you up for the method and the way of life change that quickly takes after the methodology. The recipes in the cookbook part of the book look very great and truly simple to boot.

positive
