I have been using Grandstream's for the past 3 years and decided to give the Yealink T26P a try.
Opening the box, it looks like a quality product, all nicely packaged. The phone itself looks nice, quite large and looks worth its money. The buttons are laid out well and all labels are easy to read. The display characters are large and easy to read.
While there are pages of options and settings, it was easy to setup and had running in minutes.
All in all a nice phone and will keep on using these over the Grandstream's.
