This is great to hear. The new D400 devices look quite promising on paper but I have seen virtually no 3rd party reports on how well they perform in the real world.

Are you using the D435 outdoors as well?

We've only done some quick tests outdoors for now, as our device will only operate indoors. But it works well, even when pointed into the sun. Email in profile, send me a message if you want some sample video.
