Sigma ... almost always a good thing !!!

POSITIVE:

- White version, acts contrary to the many black lamps on the market refreshingly different and high quality, ideal for white and other colored bicycle frame

- The fastening mechanism is very well thought out, just around the handlebars and press down quickly settle, let's see how long he holds

- Fixing mechanism holds the lamp in good position to improve a little handlebar tape wrap around the handlebar tanke

- I use the lamp only occasionally, was decisive for me, therefore, the use of standard AA batteries (3 pieces required)

- Despite mignon batteries I find the lamp sufficiently bright lights for 100 with its own high-performance batteries are probably more, this is probably clear to everyone

- Value for money is top!

final: All around recommendable

As always top of Amazon: fast processing and delivery!
