Hi MobiusX. I have these domes fitted to various feeders - on individual poles with feeders atop, to prevent access for squirrels from below, and for free-hanging feeders suspended from branches. Never had any problem from wind, and we do get our share of strong winds here on North East coast of England (Lincolnshire). Plus, they are very effective. Well worth the dosh! Can highly recommend them. And they last - never had to replace one yet. Regards, Neil.
