I'm giving it a 4.5 because the skirt won't lay flat from shipping . At any rate I purchased a 39" 370 Pro model with the paddle edges it was absolutely the best mini tramp I had ever bounced on . All of the others had springs . I did however realize that for my size at 6'2" it was slightly confining , so I had to opt for the 550 Pro Model . Amazon was very helpful in getting 370 Pro model returned and shipping me the bigger 550 Pro within a week . It's amazing how much better the 5 extra inches feels , plenty of room for me now. I can't understand how much better the more expensive Bellicon rebounder could be for price difference , just my humble opinion .
At any rate I am very pleased with the performance and the quality of the unit ( except for the skirt issue ) I imagine over time it will eventually lay flat. I'm looking forward to many days of happily bouncing my way to better heath in the future .

Love it- GREAT cardio workout and much easier on my knees than other cardio workouts which I also love. I set the timer for a 5 minute workout while watching tv and it IS a workout. Now, in my home gym, I do the 45 min or hour long Bob Harper DVDs (no problem). So, this is said by a non-wimp exerciser. It is different and adds to your usual exercise routine. If you have NO knee or hip problems, it is probably a great apartment or home exerciser for even longer exercise periods. As my husband was putting this together for me, he (an even more discerning consumer) kept saying "this is a quality product" It is a quality product-- VERY sturdy. I weigh 150 Lbs (I am also 5' 10" tall) and I do one legged kicks, etc. It has been rock solid for me. A friend reminded me how much I enjoyed this activity 30 years ago so I got this model. You may not need the 41 inch model- it does take up some room. With the handle bar which I HIGHLY recommend for anyone with joint or balance issues as safety feature, you are unlikely to be folding it up. Given that we are okay with this in our foyer (so I can watch tv and do my own routies), I give it a 5 star rating. Pricey but worth EVERY penny, I think IF you have balance problems, it will HELP them (unless severe, check with your doc) but please please get that handle bar. I have nothing to do with this company by the way; just love these products.

Shipping was prompt and it was very simple to assemble this by myself. Even though it's heavy duty and extremely sturdy it is quite light to move around when needed, which I end up doing every time I use it in our family's shared workout room. It's absolutely silent to jump on, which is why I bought this bungee cord- style. Side note: I have hated most types of exercise and wanted something that was a no excuses and FUN way to move my body. This is it! I watch a favorite show and just bounce around however I feel like it and I look forward to it! It can be as gentle or high effort as you need. I love that it naturally encourages me to move just because I have stepped onto it. No impact or joint pain and makes me feel like a kid! This is helping my mental and physical health a lot during shelter in place! Try it!

There is some assembly required. You have to disconnect half of the bungies to reduce the tension so you can open the rebounder. Then you need to reattach those bungies. They're tight! Ugh. Was hard on my carpal tunnel/wrists. The legs are an easy install. Probably spent 45-50 minutes to get this set up.

I've bought many items on Amazon and never written a review (which means I didn't get a discount for writing this). However, I'm taking the time to do the review because this item deserves it! I have been using cheap mini-trampolines for years. A few weeks ago, I purchased the 350 Pro, and the bounce is great, but it is smaller than the cheap versions I'm used to, so I'm returning it. I like to be able to move around a lot because I listen to music and "dance" while jumping (this lifts my 16-year-old daughter's spirits because she thinks it's hilarious). The 570 Pro gives me more than enough room to move around- which feels great. I definitely felt cramped on the 350 (I'm 5'2, 120 lbs). The 570 Pro is larger than any trampoline I've seen in stores. In addition, it is very sturdy, appears very well constructed, and I think I'll be able to use it daily for many years. Why anyone would pay at least twice the amount of money to buy something like a treadmill, I don't know! Mini-trampolines are fun, and this one is excellent! My sincere thanks to all who designed and produced it :)
