Bought the 12 foot version, 4 legs. Nice, large and high quality trampoline. Took just under 3 hours to put together (1 person job). Four and a half stars as the manual does not set out the assembly steps accurately, and the covering for the springs is not easy to get absolutely right (needs a bit of manual additional craft work). Overall good solid product & fast delivery.
Being used indoors in Dubai. Cannot attest what it would be like outdoors but for indoors it work well and surprisingly stable for use by children. Not tested it for adults or heavy persons. Would not like to risk it.
