Review: Good product - There were very good and strong but the trampoline material broke down after a year of used.will buy again. Review: Heavy duty and strong - My sons trampoline started showing signs of stretched springs on one side. Found these and ordered a set. These are some nice springs that look to be of high quality and strength. They took some elbow grease to get them stretched back onto trampoline mat but once they were all on it looked good as new. Whats nice is that they offer various sizes for whatever tramp you have.
