Initially frustrating- Amanda from customer support instantly resolved my issues following a quick phone call and a follow up email. I bought a 12 x 17 ft rectangle trampoline- it arrived being dumped on my driveway with loose springs on the kerbside (I would place the fault on the delivery team rather than Jumpking) however I noted on other feedback that this is not the first instance of such an arrival condition. I then went ahead to follow the instructions to the letter in order to construct the rectangular frame. After about 2 hours it became apparent I could not complete the building of the frame parts as directed by the instructions. I tried to contact the company via the advertised phone number and by email with no joy initially which really frustrated as my autistic son was really desperate to enjoy hIs new trampoline. I eventually looked on Facebook for other people who had similar issues and found a few who all stated the same point that initial contact with the company can be slow but problems are instantly rectified. I would give a 7 out of 10 rather than 3 out of 5 as the product is good and tech support is great - only after a waiting period that is again frustrating. Admittedly this is during COVID period and the company are operating a skeleton staff. The instructions are however pretty poor and require a rewrite. They are not intuitive and there are gaps between key fitting stages. Clearer diagrams and photos would remove most of the issues at the very outset. The advertised 2 hour build time may be what it takes practiced tradesmen but a more realistic time for families and households would be 4 to 6 hours. Overall many thanks to Amanda and the team - my son and daughter are now loving a great trampoline - clearer instructions and ease of contact to customer service would bump your rating up to an 8 or 9 out of 10.
