The reason I gave the trampoline 4 starts instead of 5 is that it is possible for someone's hand to get through between the safety enclosure and the jumping surface.  The photo gives the impression that the enclosure is connected to the mat the entire way around, but this is not the case.   I know that this is probably fairly standard for a trampoline, however I spent more on this product because of the impression given from the photo.  I may not have bought this one otherwise.
