You should do an update with JumpSport , Leaps and Rebounds and Bellicon . I think Leaps and rebounds is the best option based upon $$ and it’s actually got a decent rebound but the Bellicon is for sure the best out there but is soooooo expensive .
I have a Needak and have replaced the springs, the mat and the spring cover. But only once. Now I spray silicon on the spring contacts and there is no noise and no busting of any part either. Needak is great but I have not bounced on the Celliciser yet. I would like to but David Hall is not public right now. You really have to see these things close up before mail ordering. I have tried the 49" Bellicon (Chicago) because of its firm and soft bounce. It is better but it is very expensive next to the other ones. I think I remember the Cellerciser bounce as being stiffer than the the Needak. The Needak is the best I feel. The Rebound Air is made of plastic but has a metal price. Try them all out. Again, spray silicon on the on the spring for the noise and strength.
This guy obviously prefers spring to cord. This is why he doesn't consider the Belcon. There are reasons why someone would prefer the spring rebounders. They are better for your heath because they give a more consistent tension while the bungee cord tends to fluctuate as the friction causes heat to build up. The body then has to adjust to a different tension within the same jumping session, which is not good for the joints. .
I have tried the Bellicon at a studio north of Milwaukee and I found the 40" equal in bounce to the Needak but the 49" is superior-soft and firm. I have been on the Celliciser years ago and I remember it being rather stiff next to the Needak. I have to tell you that I tried out the Needak before I bought it and that experience sold it. Of course all the parts went bad as I described in my other letter. But after I replaced them they have stayed in perfect condition. Nothing like a bounce to really experience the thing but I don't know where that could happen. Call Bellicon in Chicago to get the address.
My Needak purchased in 2007 springs started breaking at 4 years. I didn't want to pay for replacement springs, so I bought a new Needak (but then moved shortly afterwards so I gave it to my sister). I can tell you that it would be near impossible to change a spring as far as I could tell ie you would need super human strength to stretch it. It looks like they have changed the spring design though - so I'd be curious to try one out. I have a ReboundAir that I am using now, I have used it for 5 years solid and it is still in excellent function. My ReboundAir springs don't squeek like that - I think maybe your climate and air moisture has a great effect. The plastic frame is super study, but I could potentially see an issue if I was traveling/flying with it.
coconut oil! non-toxoc. works GREAT to lube springs. Next time I think I'll do it with slightly melted oil and small brush holding a cloth underneath to catch any drips.
Bellisons are so overrated. Get a good quality one with springs for a better bounce. They are NOT that noisy and last longer. Check places like Craigslist for better deals.
He has not updated the Reboundair information on his website to show that their newer Classic model has triple tiered springs. This is why I did not purchase from him because I feel he is just trying to make commissions off the higher priced Cellercisor.
