First, I read the review complaining about the grip and "difficult assembly" and have to say they are blatantly wrong.

The grip is perfect, unless you have massive or extremely petite hands, otherwise you are golden!  It is plastic, however it is NOT slick, even when your hands perspire the grip remains non-slip.

Assembly has A BREEZE.  Two wheels two grips and one sturdy metal rod/axel.  Place the wheels on together and slide the grips on to cap both ends of the rod... that's it...

To keep this process simple and easy there are tiny holds on the ends of each grip which allows air to escape, so that they slide on with minimal force, i.e. if you have "trouble" putting this product together, you are not going to be able to perform the workout this item provides...

Seriously, I've had more difficulty opening 2 liter bottles of soda than were presented by assembly...

The workout provided by the wheel is ridiculous, but amazing.  @ 220 and 12% body fat I thought I would do "OK" when starting out (as I have never worked out with this apparatus before), but I IMMEDIATELY felt the workout and was sore within 10-15 minutes.

The motion does take a little time to perfect, and it is in your best interest to read directions and take your time to get used to it and believe me you will NOT be able to just take it out of the box and do 20 reps anyway, this thing is a SERIOUS workout.

I considered myself to have a pretty darn strong core, but after my first time, I was shocked to FEEL how much work I had to do.  This is clearly a device intended for those who are already at a tremendous level of fitness.

HOWEVER, if you are able to overcome the initial difficulties and embrace the challenge of this piece of equipment over time you will find no better way to strengthen your core, which is the best way to jump start a better overall fitness and more importantly feel better about yourself and all future workout endeavors.

Buy this item, keep your chin up and stick it out once you see how challenging it is and you will reap serious benefits.

Anyone who gave negative reviews were presumably unable to get over that hump and like most people blame everyone and everything but themselves.

As someone who is in the midst of a 100lbs + weight loss, I've learned that diet and exercise begins and ends with discipline, some people have it some people don't, if you know you have it, get this thing work your butt off and feel great as a result.  If you are the type looking for an 'easy solution' or think this is just another in a long line of crappy fads, you'll be sorely disappointed.

This thing is awesome!!!
