If your house doesn't have standard width and straight-forward stairways and landings that won't accommodate a standard gate, this is a great bit of kit. The manufacturing quality and paint finish is completed to a high standard.
You can 'configure' the gate easily to block stairs or cordon off areas and it's easy to break apart if you need to get better access (e.g. moving large items up and down the stairs).
Fixing the gate requires careful marking and drilling, but the instructions are clear. Recently, I managed to trip and break the gate's wall fixings; a phone call to the manufacturer, and the spare parts were soon on their way at a very reasonable cost.
It really is something we couldn't do without. It is versatile and I'd recommend it.
