Query: 5 Broken Springs 8 months later - totally useless now

Since purchasing this rebounder 7 months ago I have had one spring break and the bar that holds 2 springs to the center cloth piece break. There are 3 springs which are no longer attached to the rebounder. The reason I paid the extra money was for a rebounder I thought was of high quality. This has been a disappointing purchase.I've been trying to use this broken rebounder since it was past the return policy. Today on April 10th a 5th spring has broken and this is now totally useless. This is absolutely a product I would not recommend!
