Isabella Awning stoppers

DSB

Just wondered which sort of awning stoppers those of you with rollout awnings use?

When I fetched off our Rollaway awning recently, I managed to loose one of the stoppers so now need to replace.  It's only marginal, but the ones supplied with the Rollaway were just a little too big for our awning rail, so rather than codge it up I bought
some outdoor revolution 'bullets'.  Couldn't find any in our local stockists today but they did have some Isabella gadgets in.

I say gadgets, as they look far more complicated than the single bullets I have used before, but looked very good (and more expensive
).  Just thought I'd ask if anyone has used them and what they think, before I part with my cash!
