Only challenge to the designers is the display font on LCD screen is a little small, but learning to live with it. Excellent voice quality. Working with two different voip providers (one on each line) and works flawlessly. voipmuch.ca and voip.ms

The biggest things I don't like are the screen is a bit basic, I've noticed sometimes incoming caller ID is truncated. Better than it looking like a flip-phone UI circa 2001 though. An administrative concern is that it is hard to manually update the firmware on this. The firmware is openly available from Grandstream, which is nice, but there's no option to just upload the new bin file to it. It needs to be set up to a provisioning server, which is just a HTTP server, and the error feedback is pretty much non-existent. Plan to run a syslog and provisioning HTTP server for these alongside your PBX.
Overall I am pleased with it. Audio quality is good. I have a Grandstream Budgetone I bought circa 2007 that's still kicking and it feels like the build quality had improved since then, so I'm optimistic this will last.
