Right out of the box, this light looks like it has been repaired and reassembled. My previous CBL1600 broke after about a year of use.

The light works out of box with my Di2 lever, and the battery is surprisingly good. Very good product for the price.

Is there any way to disable the D-FLY CHANNELS 2/4 functionality?
I would like to use the right hood button for another device, but the EVO1700SD seems to occupy both the left and right hood buttons, making it impossible to use them with other devices.
It seems like this could be resolved with a firmware update — are there any plans to add this feature in the future?

Excelente producto.

I was blown away by the EVO 1700SD’s powerful beam. It's perfect for my late-night rides, and the different brightness settings allow for great adaptability. The build quality feels solid and durable, plus the battery life is impressive. Definitely worth every penny!

Light is very good but connecting to my Di2 worked poorly. difficult to connect and then it disconnects often. Also the flashing won't work unless turned on with the Di2. Should have bought the pro and used ANT connection.

I love this Evo 1700SD. The clean look underneath my garmin computer, the beam cut-off and the integration with my di2.

I use the left button, to control my garmin, and the right to turn on the light and to control the high & low beam.

Big wish: It could be configured to use D-FLY channel 1-3 only.
Currently it occupies both 1-3 AND 2-4 so there are no channels left for my Garmin Edge computer without changing the light too which is a bad design of the DI2 integration and not necessary for such a great device.

Super bad integration with Di2. To few options and desturb other functions... a bit sad. Light is good

Great customer service. Being able to use di2 to control the light is a game changer.

.

Outstanding light, connects to my shifters and allows me to enable high beams with my shift buttons. Amazing!

Love it, great light and works perfect with shimano 105 Di2

Easy handling, long durable battery.
Bright and homogen light.
Illuminates the entire width of the road without dazzling other road users.
For me one of the best lights in market.

Very good lighting I love it.

Great product, very bright and the di2 compatibility is great. The cover on the charging port is kind of pulling apart and a daytime blinking function would be a nice addition.

Love the ability to be able to control with the button on the hood of the Shimano. On/off, 3 levels of light intensity. Overall the lighting ahead is good, I can’t comment on battery life yet. Only needing the light for relatively short periods early mornings

Great light.
