Overall radiocodes "did what it said on the tin", I was able to get an unlock code for my Vauxhall Astra Siemens radio/CD, something that other code suppliers had told me I would need to physically send the radio to them. So it absolutely worked and very happy with that aspect. What I didn't like so much was that I got three different prices from the website for the unlock service for my radio, £24, £20 and then £22. Why ??? I'd like simple transparent pricing that doesn't change each time I visit the website. And my only other comment was that the terms and conditions make it clear that once paid for there was no refund option. Even if the code didn't work it was my risk. Appreciate that they have to protect themselves but I wanted more guarantee that I would get a working code.
