Sorry to hear about the issue with the monoblocks. I am not sure how much weight you had on your stand. Our stands are rated for 15lbs as the ad states. We have sold thousands of these 10ft light stands over the past 10 years with out any issues, if you kept the weight under 15lbs. If you put more than the rated weight you will have a failure. If for any reason you are not 100% satisfied with your stands you can return them for a full refund.
