I have the Vizy light and like it. I feel I can be objective and say I think it's a good rear light, even though I am a Tern bike owner and have been fairly active on the Tern Forum. See my comments here:

It's a decent light and has held up well. As I indicated, the circle on the pavement shows up best in darker areas, but the rear-facing LEDs are quite visible under street lights.
If you want *really* bright rear lighting, see the Dinotte tail light:
NEW 2017 Quad RED Taillight with built in battery ? DiNotte Lighting USA Online Store. My wife and kids gave me its predecessor (300R) about 3 years ago. It is *incredibly* bright; I had to point it slightly downward to avoid blinding approaching motorists. It cost about five (5) times what the Vizy goes for, so you have a choice. For the money, I think the Vizy is a reasonable choice.
