The bigger sizes can be a bit large for not being a minimum masked, mini + may be apparent without making it ugly and their white color makes them rather discrete (against white walls, of course).
For the rest, it's great. I've ordered a multi-making 4 plugs and cables which leave ... it's clean, much less "clutter" and for the household is very convenient.
The case is treated "fire retardant", which is reassuring.
So yes, it's expensive for a plastic box, but I still find that very well.
