I bought this because it looked strong and suitable for my two steps at our conservatory entrance.
It does indeed do the job. It was easy to fit and it is strong.
I've read comments that the supplied fixings are not very good. I found them a bit different from the usual expanding bolts buit they fitted fine into 12mm holes in the steps - the handrail does come with a 12mm drill but it was of the type with a rectangular shaft for professional drills so I went out and got a circular version for my Black and Decker. You do need a reasonably powerful drill to make holes in concrete. I drilled smaller holes first then expanded them with the 12mm drill.
I also saw comments that the bracing bar would not tighten properly because the square section shaft was too loose a fit and the bolts would not tighten. This is true - it needs the dimensions amended or else for the bolts to be supplied with spacers.
Finally, the bolts and nuts are supplied with a nice black finish but they have rusted within a few weeks. Not a functional problem.
