I've had one of their bike covers for years, it's been fine but it's not heavy duty. Only used it in the garage for covering summer/winter bikes as appropriate
I'm guessing you mean the
Halfords option; the btr looks bombproof. I found an old cover intended for overwintering garden furniture down the side of the house. It was protecting a rusting incinerator, which I intend to treat with a high temperature (650c) paint at some point; maybe not worth it, and I don't think a rattle can will find its target today. Anyway, despite a few holes, the cover will provide some protection to that cherished CB. I dragged the cover out, evicted a few choice snails for the Song Thrush (which, typically, hasn't shown up for the feast), and put it on the lawn, weighed down with a garden chair. Later that same day, dear reader, I looked up from my kitchen duties to see the chair cast aside by the wind and the cover airborne. Dashed outside, strewing eggshells in my wake, to rescue the cover, which is now weighed down with a garden lounger; we'll see whether it survives the night.
Did I mention that one (of two) of my carefully tended Pink Brandywine tomato plants has been snapped off by the wind? Let's hope it will now function as a bush tomato, rather than the usual cordon plant. At least there's still one intact outside, plus two in the greenhouse.
