Top Customer Reviews
I have 6 herniated and/or slipped discs and straightening of the lumbosacral whatever up to the middle of my back. Because the VA had not done their jobs right the first 5 years of my suffering I now have two enormous muscular spazzed balls on each side of my lower back at the belt line. I also have 3 herniated and/or slipped discs in my neck at the base of my skull. I am now 100% VA rated and I am now Medically Retired.
That being said, I always read the 1 star comments first to get a feel for how a product performs or it's condition when delivered. I then go to the 3 star reviews to see if there's any baseline truths to the 1 star reviews, finally I go to the 5 star reviews and see what the percentages are from 5 star down to 1 star. This product has nearly 2000 reviews and only a fraction of them are negative.
So my review of this product which I just received today after I had ordered it from amazon two days ago, is currently 5 stars and here's why:
1) When delivered there was one single tennis ball sized hole in the box which was banded really well to keep things together. I was then worried about some of the 1 star comments who had similar but more severe issues. This thing weighs 80 pounds and it's large, I see it getting easily damaged because one delivery person has to handle it. The guy that delivered mine via UPS, he was like 70 years old and this inversion table must have weighed more than he did.
To my surprise when I had opened the box there was a lot of block stirafomes (sp?) It had been extremely well packaged so as to not allow parts to be damaged through delivery. This made me extremely happy.
2) A few other reviews said the holes didn't line up, or a carabineer broke or something had failed on their table. The carabineers that I got with this table appears to be either light steel or very well made aluminum. Either way, if the table is forced to the 180 degree position (upside down) with or without someone physically on it, I could absolutely see them breaking, so my suggestion is if this is a major worry for you, go to a sporting goods store, buy two mountain climbers carabineer clips and use those. The strap that is supposed to keep you from inverting 180 degree's again if misused and/or forced hard I could see that breaking too especially for some of us larger guys because i'm sure the strap is only rated for 300 lbs maximum 350. It's not flimsy but it's not a tow strap either. If this bothers you, go to a hardware store and buy some chain links, you can adjust them by clipping through various lengths of the chain.
3) Some reviews said they could not put it together because of misaligned holes or it takes to long or I don't have someone else to help me put it together, etc. My comment, you must be a moron if you can't figure out how to put this thing together, it's certainly not rocket science. The directions show you EXACTLY step by step how to put it together, heck you don't even have to be able to read, just look at the flipped pictures. Anyhow, the directions say it will take you roughly 60 to 90 minutes to put it together with help from an additional person. I put mine together in 23 minutes all by my onesies. Truly not that difficult!
I realize I've only had this table for one day at the point of this review, I've used it 5 times today in intervals of 5-7 minutes. Probably too soon to comment on if it works or not, but the first use, I could feel the extreme pain as I was roughly 130 degrees inverted. PULL YOURSELF UP SLOWLY OR YOU WILL BE DISORIENTED AND OR MOTION SICK! I did that and the room spun for a minute because I pulled up to fast. The boots that keep your feet held, I think those things are more comfortable than my 90 dollar sneakers, I used it 3 times without socks or shoes! I hope I can come back to this posting to re-comment and/or edit in the near future after several uses to let you know if it worked for me and or if the carabineers and/or the strap breaks. Even if it breaks, you can still pull yourself up with the supplied hand bars on both sides, so those that "freak out" if this happens, grow a pair, calm yourself and use the hand bars! Oh yeah, as for the bar that you close which has the shin boots, seems like it locks extremely well to hold you safely in place. There's also directions in the book that tells you what to do IF it seems like the bar wont open, hasn't happened to me... yet? I guess if it does I have a pair so I won't be freaking out, it's a simple push the plastic head down, twist it either direction, then pull it up towards your torso and push back down to open it. It seems like there are quite a few safety features that keeps this thing from inverting you by accident, even the bars that hold the table to the lower frame can be adjusted so as to not make you completely inverted if the belt breaks.
I know there's a lot to read in this post, but I sure hope it helps you decide if this is for your or not. If you want photo's of this product close up I will be more than happy to post a few.
Once assembled, the Gravity 4000 seems to be a good, solid inversion table. It does what it is supposed to do and actually performs very well. I have no doubt that it will actually support 350 lbs as advertised. I do have some concerns. First is that the two primary pivots are just metal-to-metal. There are no ball bearings or any type of real pivoting mechanism. Despite that, the table seems to pivot well enough. I just wonder how long a system like this will last. Another concern would be with the plastic bushings around the main shaft. I'm not sure how long they will last either.
Within a week after buying my Ironman table, a local Sporting Goods store ran a close-out special on Teeter Hang-Ups' NXT-R Inversion Table. The price was very good and the unit was so attractive, that I went ahead and purchased it. Now, I have two Inversion Tables. That either makes me stupid or a good little consumer. Either way, my Family Room is getting a little crowded.
A few words about the Teeter Table: The difference in quality of packaging alone made a huge impression on me. It is obvious that Teeter's packaging was carefully thought out. The individual pieces were in plastic bags and the inside of the box was blocked out with corrugated dividers. Unlike the situation with Ironman's packaging, none of the parts in the Teeter box were damaged. Teeter also includes a DVD which details the assembly process and contains lots of information on using the table as well as general tips for taking care of your back. That's a nice little added feature, but you do pay for it.
Since, for the time being, I have two inversion tables in my home, I have been able to do a side by side comparison. Here's what I found: The Ironman's ratcheting ankle holder is definitely easier to use and more comfortable than Teeter's system. It has a long handle and you don't have to bend over as far or exert as much energy to lock it in place. As for overall construction, the metal parts are well made and the unit feels exceptionally sturdy. I am concerned that the plastic parts (bushings & spacers) might be easily damaged. As stated earlier, several of these parts were already damaged when I opened the box. I am hopeful that all of the plastic components will hold up well over several years, but only time will tell.
The Teeter unit appears to be a high quality item from the minute you open the box. (Good packaging makes a real impression on me). The only thing I wound up changing on the Teeter was the ankle holder & main shaft assembly. The original ankle holder was just a foam covered bar. When I tried to use the table, the bar put so much pressure on the top of my feet, I could only use the table for a few minutes before having to get off to relieve the pain. Ultimately, I contacted Teeter and was able to "buy" a replacement main shaft with an upgraded, ratchet style ankle holder similar to the Ironman system. Teeter's customer service wasn't nearly as accommodating as Ironman's. They charged me $100 plus $30 shipping for the replacement shaft. I was hoping their 5 year warranty would cover the replacement, but no such luck. They do offer a partial refund if I go to the trouble and expense of shipping the original assembly back to them. After resolving that one issue, I'm now much happier with the Teeter. The Teeter's construction and function are all top notch, but again, you pay more, so the quality is expected. The Teeter that I frequently see advertised on TV appears to be a lower grade unit than the NXT-R model that I bought.
One other thing that I should mention is price. The Ironman Gravity 4000 table retailed for under $200 on Amazon. The Teeter table that I bought locally retailed for well over $400 (I got it at a close-out price of $279). Add to that, the $130 I paid for a new main shaft & ankle holder and I now have over $400 invested in my Teeter table.
My conclusion is this: Ironman makes a very good inversion table. For less that half the price of the Teeter, the Ironman table seems like the logical choice. Actually, I have no real regrets about buying either table, but Ironman definitely gives you more for your money. Teeter's 5 year warranty and overall quality are great, but remember, you pay dearly for Teeter's extra features. Also, Ironman's customer service was happy to replace my damaged parts without any warranty concerns. For now, I'm going to keep both tables. I'm still trying to decide which one I like better. I can say that even after replacing the ankle holder on the Teeter, I am more comfortable on the Ironman table for longer periods of time.
I'm not sure if this review will help anyone decide between the two tables. In my opinion, you won't go wrong with either brand, but the Ironman is definitely a better deal.
When it arrived, it had a little plastic part that was broken. I've attached a picture. I was able to reach the customer service team quickly and they sent the part to me by Fedex. Amazing service. Since I live a mile from nowhere, it took a while for me to get it. But that wasn't their fault. They responded immediately to my concern. It's rare that I find customer service this good.
I've included a picture of the part that was broken. I went ahead and installed it anyway while waiting for the replacement to come. It was actually real small and very easily repaired.
Not only did they send me a new one, but they sent me several extra in the event that I needed It.
This is a fantastic, high quality machine. And I'm very happy with my purchase. Knowing what I know now, I wouldn't hesitate to buy this again in a heartbeat if I needed to.
After getting the parts today I upgraded my review to a well-deserved 5 stars.
