It does work if you use it like everyday and combine with exercise and healthy eating i been using it for 2 weeks and i can see the difference that i was not able to see just with exercise, and you can use different modes batteries last for long time (i had not change mine since the beginning and i use it every day).
I have been using it for approximately one month and noticed the change on my stomach. I will use it 24/7 until I have the body I am looking for. To have a Perfect stomach.
Its really quite taxing but its day 7 now and already definition of the 1st set of abdominals can be seen!. You will discover muscles in your abdomen you never knew existed.
Nothing I don’t like about it yet except maybe hooking up attachments but that is pretty minor. This is a fantastic piece of equipment that is convenient and effective to use. I love how you well they pack up for travel also. This is now my third one I have bought, the second and third are the OYO BLACK which is much better than the red one I started with. I keep One in a second vacation home.
The zipper are beefy and everything shouts military grade. The Fabric is thick, strong, and durable. The external pockets(many) have redundant straps. Despite more than 600 orders I never wrote a review as many people seemed to know much more than I. Despite some negative reviews I ordered this pack for a 30-day AMTRAK trip.
