Question: The feet on this leave black marks on my carpet. Is it the particular set of feet that came with mine, or do they all have the potential to rub off?
Document: Apparently, these trampolines are to be used for hopping daintily during an exercise routine, but let's be serious. Kids find it more fun to jump on them. And mine JUMP.In SIX MONTHS, one bungee came unsewed, two bungees broke, and the rest of the bungees have stretched out so that it doesn't bounce properly.In their defense, JumpSport gave me a new mat and four new springs under warranty.
My feet just didn't.I will add the jumping area on the mat of the jump sport is a bit smaller then the Bellicon. The guy at the fitness store said with feet that pronate it is actually a better thing. Apparently the larger the mat, the more likely feet that pronate, are going to turn in and you will sink down in the middle of the mat. I'm still able to do my little stunts on mine though.
It did have a stabilizer bar on it. I did the health bounce while the manager took care of some customers. By the time he came back over to me 30 minutes later I was bouncing all over the place with it. Feet off the mat, even doing leg cross overs and jumping jacks. With and without shoes.To try to shorten this, I ended up buying the Jumpsport 220 with handle bar. Cost me about $ 267 with tax. I thanked the guy for letting me try them out.
With bathing suit season coming up I wanted to look my best, and work off the pesky baby weight. I haven't had my jumpsptort long but I already feel a difference. It took only 10 minutes to set up and and came with a great work out dvd. I feel that this in tandem with weight training will have me whipped in to shape in no time. the plus side is its all in the comfort of my own home.
Now we don't know what to do because the website doesn't list this particular thing (the whole mat, I suppose) in their "parts" section and Lord knows how much it costs. We are very disappointed that this thing isn't more durable. :(
I like the fact that this thing is soft to bounce on. Low impact is important to me.The thing I don't like is that the products are only offered in black. It takes up a lot of space in a small room and I don't care for black to start with.I would recommend it and would be really happy if a light color was available.
I really love this trampoline. I have been using it for two weeks now and I already have noticed a difference. The only thing I have negative to say is that the legs don't fold so it is a little bulky. I keep mine on the treadmill when not in use.
I was fully wanting to get the Bellicon after seeing it on You Tube and commerical websites  and some guy on You tube comparing the two. Although the price was killing me. I wasn't about to take second best, (the Jumpsport.) My health was most important to me. I even had the color picked out. The black and orange mat and orange bungee cords. It made me feel energetic just looking at it.But something told me that I should at least sample how it felt.
I take good care of my equipment and my bungees have never broken and appear to be in very good condition still after more than a full year of use. The frame and platform are very well made and I think will last a long time with decent care. My brother liked mine so much that he has one too.
A family member of mine purchased this trampoline. I loved it. Went home and decided I wanted one, but was obviously a little flabbergasted by the price. Purchased a far cheaper alternative - returned it the same day. This is what trampolines should be like. Don't settle for anything else. Highly recommend.
