A wonderful range of feeding devices, nest boxes etc, for our feathered friends; The Squirrel busters are remarkably effective and can be adjusted to prevent squirrels and larger birds from accessing the feeding ports. My first purchase, over a year ago was the peanut version, so good that I have now purchased a second plus the new suet version. Should any mishaps occur, as when I stupidly dropped the earlier buster some time ago; following a phone call, a new part was speedily sent to me. The range of nest boxes is superb, unlike many on the market that are totally inadequate and badly made. Good range of feeders, foods etc, for diverse forms of wildlife. Highly recommended!!
