Firstly, after I bought my Azur headlamp/tailamp pack, it said fully charge before first use. I rang to ask a question on how do you know when it's fully charged. The girl didn't know but promised to try find out and ring me back. She never rang back. I had to ring again several days later. Secondly, I had to ring about 8 times because the phone went unanswered. I ended up taking Option 2 Service, who answered straight away. I was then transferred and the guy then answered my question for which I was awaiting. Thirdly, the instructions on the Azur pack were very minimal and only just helpful but not much.
