Bluespark Tuning Box

Wondering whether to get a tuning box for a 2014 A6 2.0TDI Ultra (190bhp), seen one sold by Bluespark Automotive has anybody any feedback on these boxes?
Thanks

hi yes stoney i have been using a bluespark box for over a year, they are very helpful, and now having changed my car they have reprogrammed the box for my new car, only had one issue with it of my own making and sent to back to them to look at and no charge checked it fixed it and never had an issue since (the issue was i didn't secure the cable to the box )
