Darchen 450 lbs Mini Trampoline for Adults, Indoor Small Rebounder Exercise Trampoline for Workout Fitness for Quiet and Safely Cushioned Bounce, [40 Inch]…

I did not expect the assembly to be easy based on other reviews. I was not disappointed, it was extremely difficult, took a lot of strength and at times I wanted to give up. But I did it by myself (64 yo female) and had all but 2 of the bungees in place in the same day. The next morning I came back with renewed strength and got the last 2 placed. I have been happily jumping ever since.A couple of things I learned along the way. The frame does not snap firmly into place. Not sure why it was made that way. But after I assembled the frame and attempted to put on the first few bungees the frame kept falling apart (its 3 pieces that make up the circle). The youtube instructions said to assemble the frame then put one bungee first on north, then south, then east and west. The guy did not address the frame falling apart issue and this is where I almost gave up. But thankfully I persevered. Before I put on the west bungee I noticed the frame was getting sturdy but one piece was again disconnected. I had to give it a lot of strength to push the steel male part into the female part. Once I did that and had the first 4 bungees connected the bungee force/counter force held the frame together and it was never a problem after that. If you don’t understand this right now, you will when you start to put it together. After that, I followed the instructions of putting a bungee on every 5th slot. The best tool for me was the long almost rectangle one. That one did not pinch my hand at all, the other tool did. For my model, the instructions for the rectangle tool are not in the instruction manual but are on a little post card that you could miss. I saw that about halfway through and it made the job much easier even though still requiring a lot of push and pull strength. Now I love this rebounder so far. It is stable, has great jump capacity, and it’s silent. It does not fold up but I want it where I can see it so I will continue to use it. Time will tell if rebounding is my key to optimal health. But so far I am happy with my purchase.
