Large

I liked this product a lot. But I should have measured what 40 looks like. I live in an apartment so it takes up a lot of room. Takes 2 people to put it together and doesnt fold up unless you are dismantling it to a degree. The rail is adjustable which I like a lot. I love that it is easy to jump on and excellent quality. Love it.

Simple set up

Just received it today, so havent had the chance to fully use it. But set up was super simple. Better directions.

Nice product

I bought this for my son, and he loves it. Ive used it myself a few times and am happy with it. My only complaint is the handle doesnt quite fit tightly enough and can rattle when jumping, but otherwise it was a good purchase. Very nice.

Good Value

Good value for the price. Easy to assemble Would definitely buy again.

Good quality for price, but

I bought this mainly because it showed it was fold/able, easy to store when not in use. I do not have a space to keep it fully assembled so being able to fold it and store it away was important. Disassembling it is just as laborious as putting it together. And you will need to do this every time your want to use it, then store it. It is not convenient if you have a small space and cannot keep it assembled. If you have a room just for exercise equipment or room in a garage or something it is perfect. I put the rebounder together myself, a 5 ft. 3 tall (short) female. Instructions werent perfect, but I made it work. I will probably never use it again as I do not have the time to assemble this thing every time I want to use it for my 20 minutes a day. It takes longer than that to assemble and disassemble. If all I had to do was remove the legs and fold for storage, it would be do/able. I am definitely disappointed that this will not work out well for me, however I do recommend it for folks who have the space to keep it assembled. It is surprisingly sturdy and really gets the heart pumping, even at a low pace. I believe it is a great product, but it would be an excellent product if the storage process was easier and compact. Easy to assemble. Very sturdy.

Low quality bungees

The Bungees are not as strong as I thought they were. I weigh 144 pounds, so its not because of excessive weight. I Received it on the 26 of July and kept it for about three days without using because I couldnt install the handlebar. Two screws are missing and the holes dont align properly. I had still decided to keep it, but I used it for less than three weeks and a bungee already snapped. Very poor quality. Money good to have.

Beware

Note the instructions say two adults. You need two STRONG adults. Its spring loaded and dangerous. When assembling it my partner lost his grip and the frame hit me in the head. Does the job.

This is good for someone who is new to working out on a trampoline.

This was easy to assemble but I needed two people to do it. I think it would be to much work to fold it after every use if you use it often. Buy it again.

No way to put together by yourself

Too much strength in the unit to be able to lay out flat by myself.

Some of holes for the screws are misaligned by as much as 45 degrees

The defect in this product is the E/bar holes. The holes are misaligned by 45 degrees preventing the handle bar (labeled C) from being attached. When the E/bar holes are screwed in, the two E bars point inward, not horizontal to each other for placement of the C bar which you hold onto while jumping. Also, the mat that you jump on is raised some six inches all around the edges, creating an unsightly appearance instead of laying flat like the ad pictures.
