Can’t comment about mister part but ladder is great addition to trampoline and does what it suppose to. Was quick and easy to put together , satisfied with my purchase .
The ladder is not good to use for little feet as it can get slippery. The mister did not ever work and just sprays a straight stream which makes the trampoline very wet and slippery. Not worth the extra money.
The ladder fit perfectly on our 15' Propel trampoline. No more using a chair. Its strong and held up to lots of traffic this last weekend. Kids, moms and dads used it. Some of us are bigger than others and it had no issue doing its job. Have not hooked the mister up yet. I dont see it being an issue. Very straight forward istall. Maybe next weened if its warm enough outside to news it.
