A bit low when not in a relatively bright area (say a house during the day without lights on), but that's largely solved by the backlight or a small tilt to catch light better. And in direct sunlight it's excellent.

The display isn't as nice as Pebble Time (fewer colors, more directional, overall slightly dimmer) but it's more than functional enough. Transflective is obviously the right choice for watches, I don't know why everything else has gone for phone-like panels that are often unreadable and kill battery life.
