I picked these up to go along with my RGB Panel Pro to use for product and food photography. The lights themselves are very easy to use and helped me achieve my goal of a soft "candle light" glow appearance that I was hoping for during my initial shoot with them.
The lights are very sturdy, and the addition of the magnetic ends will be very useful in mounting them overhead for some top down lighting.
The only real complaint I have is not with the lights, but with the app itself. While the new app is still very easy to use and switching back and forth between my two tube lights isn't an issue, unfortunately, it doesn't support my 2 year old RGB Panel Pro. Yes, when using all of my lights, I can switch back and forth between the two apps to set the lighting, it would be nice if I could control all of my lights from the new app.
