Can I just say that I have the 'old' version of the UV lamp and it works with Minx just FINE. The new one is just more robust and has a dimmer which is cool and both those things make it more expensive. As you would expect really. However the other lamp works perfectly well just without some of the refinements.
I didn't know that the old one would work perfectly well. I was told at the event that I needed to send my black one back as they were going to be recalling them but they would send me out one of the new lamps.
