Question: It's true that it includes a exercise dvd and hardware? I'm wondering if it will work for a 5ft tall person? Thanks for your answer..
Document: Now I have to make a trip to the hardware store and buy a replacement screw. Hopefully it will work well but be aware...no quality control at all.
that all i can said.i did not used it a lot but when i used it,i can feel it work............................
cant use it. bought it because it was adv as &#34;like new&#34;, when I received it all the hardware was missing along with the headrest. had to throw it away
No need to spend money on more expensive models - they all work the same way, and if you need additional support or cushioning for your head and neck (which is really the only way i can see this thing being improved), simply wrap a hand or dish towel around the head piece.
Wife was all excited to get this and when it came she couldn't put it together. The box was trashed and all the screws as well as the dvd are missing. She needed it for her trip tomorrow Tuesday 7/30.
It feels totally comfortable on my neck area, easy to put together and really works the abs when doing crunches.The one downfall and its been mentioned before it may slide a bit if on a slick floor. I bet if you used it on carpet it wouldn't at all.Over all i am happy with product, its a nice change from regular crunches, decline crunches and exercise ball crunches.
Works Graat! Just had lower neck/upper back surgery on 11/07/13 & when my Doc let me off my leash to go back to the gym, sit-ups were KILLING ME! Nasty pain someone sugested one of these & it works great! Gives support where I need it & I'm still gettin the reps in now without the pain!
it does what it needs to dothe padding on the frame feels comfyand everything feels solidgreat buy
for the price and seeming durability this ab roller is going to do what I need but we'll see later if the thin tubing will hold
What comes in the boxExercise DVDAb rollerHardware and screwdriverAssemblyAssembly was intuitive and it took 10-15" to get this together. Unfortunately, this item cannot be folded or disassembled easily for a more convenient storage, such as under a  bed.UseThe head/neck padding is comfortable. There are multiple hand stations for more flexibility. It helps eliminate neck strain when doing crunches. The construction is well designed and the setup is ergonomically sound.ConstructionThe padding is firm and is covered by vinyl.
