Received the K7 mini on Monday. As Zach mentioned, no import fees were charged (Canada) - appreciated! I've been testing the light for the past 3 days. So far it is operating well without issues. If I unplug the light, the previously saved settings are restored. The fan noise is reasonable but doesn't come on too often since I'm not running at more than 50% intensity. Construction seems good but I can't speak to the quality of the electronics used. Overall, very pleased with the light so far.
The software is the weak point. The UI and feature set is basic. A bit of investment in this area would greatly improve the user experience. I'm connecting via AP mode to change the settings (works well). Wasn't able to connect successfully via LAN - there are a number of tips on several threads - but I might be out of luck since I'm running an updated iOS device. I think new users will likely be a bit frustrated with the initial connection with the app but some perseverance will get you there.
