Bought these to fit around downlighters from above in my loft space prior to installing more loft insulation. The instructions were not very easy to follow and, like some other users, I found that the perforated slot for the wiring at the top was in the wrong place compared with the location of the wiring and sprung legs on my downlighters . The solution? Cut a slot in the right place with a pair of kitchen scissors. I then found that the large rectangular holes were not large enough for the black electronic box on top of the downlighter so I had to cut more out of the slot with my trusty kitchen scissors. Just as well these diffusers are made out of very thin metal. Finally all cuts had to be covering with insulating tape to prevent the sharp metal possibly cutting into the electric wiring/black box over time. I bought these because they were supposedly Building Regs approved. Whether this is still the case after all my additional engineering I doubt. I assume they are still better than nothing but they were not straightforward to install as you can probably tell by my description

Perfect and simple to use

Had to trim them slightly, which was easy so nothing to worry about.
They were simple to fit too.

Great Purchase

Really simple product to install and love the fact i could install it from the room below instead of trampling around all that loft insulation. Also, love the fact the Diffuser is adaptable to different diameter sizes of downlights because having many types in my ceiling, it wasn't necessary to keep thinking of matching which light to which diffuser.

Finally, having just purchased a house with an NHBC guarantee i was worried about using methods that would invalidate my guarantee. So i was thrilled to discover this product had the approval by them.

Poor design

This may fit some downlights but not my recent fire-rated ones, even though it claims to be suitable!
I followed the instructions precisely.
Firstly the upper slot through which the junction box is supposed to protrude is far too high ( by at least 5 cm). Secondly the horizontal slots that are supposed to engage with the downlight securing clips are at 90 degrees from the position of the clips on my downlights.
These will NOT fit some downlights.
Pity because it would be very useful
