I ignored all the history and threw the jawbone especially excited by the product in response to some criticism on the net. The product is praised. 10 days of battery life, a more accurate pedometer, a sleep monitoring system, a smart alarm short on paper, a bomb.
I receive the product. Wow! We see that the marketing department do not laugh. A beautiful green transparent plexi perfectly highlights the bracelet.
A nice booklet as a multilingual instruction whose content is worthy of note in 20 that I gave above for the product. But nothing is translated into several languages.
In short you download the app, a nice home screen, a page that says "press the button on your band up and watch for the light".
with a beautiful image of a pretty green up and loupiote.
I press the button and I have not this pretty green flower as in design ...
A vaguely red thing with little things inside that green flash twice and then nothing.
My Small precision load up well (unlike many others) and it was loaded before doing the manipulation.
So after 20 mins trying on different android mobile. made of soft reset, the hard reset, instruct the harbor on the USB PC / Laptop / wall charger. I decide to return the thing at amazon.
It took me 5 mins amazon sends me another I go up to bed.
The next day a little frustrated with my experience I decided to go for a ride on the jawbone of fofo for up, And I understand my mistake.
Reading their forum makes everything very clear. This product is a calamity.
You can read reviews from people who are in their 4th bracelet 3 or 4 months. Certainly jawbone apparently relatively easily replaces its products. But 3 or 4 substitutions within 0_0 months. Then browse the forum (troubleshooting section) to fully take the measure of what is happening. This product is not sold millions of copies.
Go also take a look at amazon.com (not .com) just to see some users opinions.
Short 24 hours later my second bracelet happens ... Same scenario, same thing.
So unless you are players, because apparently there are sets of jawbone less rotten than others; by purchasing this product you have a high probability to sit gently on the worst 129 euros or come what may at best.
Although this product is very appealing, even if there is a probability of hitting a functional product (at best a few months) I urge you to avoid this expensive thing. The nike fuel band for owners of iPhone and Fitbit flex are alternatives. But the jawbone up is a farce.
I want to thank amazon for its outstanding customer service, but I also invite them to remove this product from their catalog.
I recall going to read the jawbone forum for users of up and jetew a look at customer reviews on amazon.com before making your purchase.
