Input:
Question: I have a 7 inch wrist, should I buy the 7"small or the 7&1/2" medium? Not sure if it is better to have it just fit or have some wiggle room?
Document: The product came very fast, and it looks great. The reason I gave it 3 stars is because there is a small defect in the silicone on one of the holograms. I just wear that side on the inside of my wrist so it can't be seen.
But there has been way to many people that I have talked to that can tell the difference (some with energy, endurance, and pain relief). Even if I haven't swayed you opinion and you just think there's a 1 in 5 shot that this thing really works it still a relatively small one time investment/gamble for your health. Granted the science isn't common knowledge but that doesn't dismiss it's legitimacy. Anyways hope you try, love it, share the good news about it.
Simple as this: I use it for motivation. Do I believe it does anything? - No, but if you want a comfy bracelet that will remind you everyday you can jump higher, run faster or balance on 1 foot and looks cool at the same time I say buy it.
Ummm...this item fell apart within 2 weeks, and I didn't do any crazy activities either! Hopefully the places that sell these make better products or I will not order from them anymore!
This thing actually works!!! bUy it it is awesome!!!!!!!! Mot a rip off!!! Buy the clear and white. But buy the small because it fits for all sizes!! !
I just received mine and feel better than moments before, I feel more relaxed and seem to have more balance which has been degrading for some reason. The shipment came faster than expected and no problems what so ever with the product. For the small price I paid is more than worth it for me. Since I do feel a difference than before I got it.
The company is also being investigated here in the US for false claims & have already been busted in multiple other countries.If you want to improve your life, athletic performance, etc... "Breathe" Oxygen is the single most important fuel to our body. When you breathe shallow & short a limited amount of oxygen gets to your blood stream. Take a deep breathe & pause 1-2 seconds before exhaling and watch your mind & body improve!
My run times have improved and I feel better after I do run. It is because of the "Power Balance", or just the fact I have been running more? Who knows, but it is kind of cool to think the bracelet helps. Also it is a great conversation starter. I have met a lot of cool people who ask about it. My grandmother use to wear a small magnet around her neck because she said it made her feel better.
And the last is just simple stretching, he has him not stretch once, but a few times by having him moving around, so by the final 2 the muscles are starting to stretch better. If they have you do it a 3rd time they would likely get a bit more movement even.
I sent mine back for a refund and i hope you all do too, or even better yet, don't buy one here because, this price, is too good to be true.
