It was very helpful. My shoulders, arms and back muscles are bigger and tight. Let me start first by saying that this will probably not work for anyone whose severely over weight. Abdominal muscles are tighter now. My guess if you're fit and want to maintain like myself or getting down to near your target weight with exercise and good diet then this is definitely for you. No manual. I googled manual on YouTube. I love it. I love this device. Hard at first but after 3 to 4 weeks became easier. Great workout.
Fits great! It’s very bright but she LOVES it! Very pleased. Bought this for my daughter who wears a 0/1.
The backpack I got is black with the brown straps. Well, it does just that, It has padding on the part that touches your back which is comfortable and 2 compartments for a water bottle (something JanSport doesn't have-- at least on what I had). A little bit about me, a college freshman, recently used Jansport, pre-med turned English major, 5"3 tall. but, aesthetically pleasing to my eye. I got this backpack hoping it would fit my HP Spectre (15inch) and be able to hold a day's worth of classes without hurting my back. I was looking for a laptop backpack that was big enough for me. The Jansport backpack I have has barely any space, lacks a laptop compartment, does not have a place for a water bottle, and the zippers keep getting stuck on the material which has begun to become the biggest nuisance of my life. see pictures.
Super comfortable. I used this as my carry on when I went to Thailand. Holds so much stuff. I haven’t gotten it wet yet but it is soo roomy.
Only drawback were the rocks getting caught in the grooves in the bottom of the shoes but again they were meant for water activities. I wore these shoes on an excursion. I didn’t get a chance to wear them in the water but they were pretty sturdy climbing up the temple and hiking! They aren’t built for it but they withstood and are extremely breathable.
