Excellent Trampoline, Substandard Installation – I had my trampoline R54 installed today - it is a beautiful trampoline - and is worthy of five stars without a doubt. However, there are issues with the installation. Firstly, I was told two installers would arrive, and only one rolled up, which meant I had to help move things around which is what I was specifically trying to avoid due to my bad back. Next, I am told that the accessories I purchased, such as the ground anchors, are my problem to install. The trampoline also comes with FOUR bags that are meant to be filled with something like sand or dirt, and I was not assisted with this either; nor was I told beforehand so that I had some sand or dirt available. The installer did construct the ladder for me but didn't even open the box with the shifting wheels. IF I had been told this all beforehand I probably still would have had it installed, but perhaps not by their contractors, or else would have negotiated for them to do these other jobs as well (it IS $150 for a 30min job); I would have had sand ready and available. Someone above said that the review was not helpful as it was about the installation, not the product, but remember that the product is actually rather difficult to install (the video is >20mins, I am an engineer, and was still not willing to do it), and I suspect most people will also purchase the installation.
