This review is for our 2nd 15ft Skywalker, not our first Skywalker trampoline.
Our first 15ft round lasted over seven years. It was still in relatively good shape, but our daughter who uses it the most was in high school and we felt that because she was older and heavier, that we didn't want to risk any injury. The frame was still in great shape as was the mat and springs, but we felt that since it had seen a lot of usage and weather that we would get a new set up. The cost of a replacement mat from Skywalker wasn't much less than the cost of a new unit from Sam's.
The new 15ft unit went together easy, as did the first 15ft. The new unit saw the same usage and wear as the first, however, there is a huge difference in durability which has resulted in this review.
Less than one year, the mat developed a very small hole, about 1/4 diameter. Since it was still less than one year and the factory warranty in affect, I contacted Skywalker. I was told that "soft" parts such as the mat and springs only have a 90 day warranty, so the mat was no longer covered. I was offered a discount on replacement parts, but didn't use it. I waited to see if the hole became larger, which it did not.
Maybe six months after I noticed the hole, I started noticing springs laying on the ground. Springs were falling off because the triangle steel spring-mat attachments were tearing away from the mat. The stitching is failing causing the fabric strip that attaches the steel triangle ring to the mat. It wasn't happening at a specific location on the trampoline, but randomly.
I am extremely disappointed in the quality of this second Skywalker trampoline. There is a huge contrast in quality between our first unit and the second unit. I'm pretty sure that the second unit was made in China, I no longer have records for the first unit, so I don't know the origin of manufacture.
If you purchase a Skywalker, keep an eye on the parts during the first 90 days and get them covered by the warranty.
