Aside from some very esoteric (and expensive!) shock mount solutions out there, this is about as good as it gets. I now own five of these, and confidently trust them with my vintage Neumann SDC's (I use Rycote's for my Sennheisers, but that's simply due to the smaller form factor).
Rubber bands may need to be replaced over time, but that's common. This is a very versatile, durable shock mount than lasts for a long time.
