DO NOT -- I REPEAT -- DO NOT WASTE YOUR MONEY!!!
This product is not worth $135! What you see in the infomercial is not what you will receive. The device is made of lightweight plastic and do not resemble the advertised product in any way. It's cheaply constructed and weighs 2-3 pounds at the most. I was so disappointed that I returned it via UPS the same day that I received it!!

ab rrrrrocket
i'd give it 3 and a 1/2 really, bc it certainly does the job, which is the main goal. but if you are too tall or too short, it's not as easy. my fiance is too tall for it and he doesn't like it. i'm on the short side and i find that putting a pillow on the seat helps it from hurting my back as i roll up, it's hard enough to keep my head in place. BUT you really feel the burn. if it were designed better, i'd give it more stars. you can def do way more crunches, etc. with it than without!

Effective for creating abdominal strength
I am not a paid reviewer, that's for sure. I looked at the Ab Rocket with a lot of skepticism but with the simple hope that it would work as advertised. This product does work if you use it right. Initially, I approached it from a typical sit-up perspective, but that wasn't the right way. This is good for crunches, not sit-ups. It makes them easier and definitely more fun. Watch the accompanying video and they'll show you how to use it correctly. Actually, I didn't get it till I saw my wife using it, then the light came on. So, first off - it does work. The other good thing is it really is lightweight and relatively easy to set up and move around. It's true as some have said here - the resistance coils do take more effort to change than I would prefer (I needed to use a pliers, actually). But I've had all kinds of exercise equipment and they've always been heavier, bulkier, and more difficult to manipulate than made to appear. This only weighs 10 pounds, so thankfully, this isn't like them. Is it worth $100? I say yes, because it isn't about the value of the materials so much as it is about the value of its effectiveness. Can you get anything else this effective for even near the same amount of money? Not that I've seen. So, if you want an effective way to create abdominal strength then I say this is worth the money they ask for it.

Helps me do sit ups again!
After dislocating three lower back disks over the past 20 years, I pretty much gave up doing sit ups. When I saw this product I thought it would be just like all the others: overpriced, uncomfortable and useless. Guess what ~ I was wrong! I'm using AB ROCKET happily now for one month and have more praise than criticism for it. At just under 5'5" tall, I fit comfortably, however, I could not see a person taller by even three inches getting any benefit out of the neck support. There is no strain on my lower back whatsoever, so the design does what it is supposed to do and I am doing 100 sit ups a day, feeling the results within no time. For me this was the biggest plus since I could not lift my back off the floor for traditional sit ups without the aid of this rocking device. Highly recommended to anyone looking for a basic abdominal workout. My few criticisms were that the three resistance bands were pretty much useless in terms of the lowest being so light it was light having no resistance at all, the middle band not much tighter, and the "hardest" level was just about right. I'd have liked one even harder. The other negative point is that in order to fold the unit for flat storage, you have to unscrew the tension springs, and the plastic caps are not sturdy enough to withstand daily usage. The model in the store already had two broken caps so I'm being extra cautious with mine.
I would NOT shell out the price on tv plus shipping for this, it's just not worth it. But the price here on Amazon is more on target with what a simple at-home machine should cost.

Resistance
The Ab Rocket is great in terms of the idea of having the head and neck support. In addition it allows the lower back to avoid excessive strain. However, the resistance for each of the various springs seems to be that same regardless of the color spring used. As noted when viewing the demonstration tape, clearly the springs that are on the model are more resistant as the springs actually cause the ab rocket to pull forward. This is not the case when actually using the springs provided. After a few uses it will be necessary to obtain addtional springs that have a tighter fit thus providing greater resistance.
