We’ve been in production of the LaunchPad training aid for nearly 8 years now! This product has a 100% durability rating, as in all these years (nearly 300 units sold)- NOT ONE LaunchPad ramp has failed, been damaged, broken down, or in need of replacement. I still have one original ramp here at Malone College, manufactured nearly 10 years ago. I’ve purposely left it out in the heat of summer, and harsh cold of winter. The top is still solidly connected, the only thing I’ve done to it is replaced the spikes! This product is definitely worth the cost- You’ll NEVER have to replace it! You can’t say that about many other pieces of equipment in your shed.
