We installed around 35 Sirius DL7-1400 six months ago. Could be happier - they are much brighter than the previous Halogen and haven't missed a beat. They were the third led downlight we trialled and quality was substantially better than the cheaper ones from other manufacturer. We couldn't be happier and will shortly replace the remaining lights in the house.

Nine of the lights are on dimmers and work very well.

Only minor negative is that one of the drivers didn't work but there was one light we didn't install so not a big deal and Wattsavers happy to replace it, I just haven't got around to it.
