Quotes from the Reviews - What People Say about:

Battery

Battery:
"I bought this device off of Groupon it's very comfortable the battery seems to last okay the only problem I would say is that it didn't track my sleep without me messing around with the settings other than that it's a solid piece of equipment the app is free but it's pretty solid piece of equipment."
_
"At first it worked very well, but now after a couple months of use it has broken by the battery charge part and will not charge."
_
"However, the Pulse is not great on battery life and the clip and or band doesn't hold the device securely enough and I lost two of them."
_
"When I turned it on, it blinked between setttings and the battery went completely dead."

Charging

Charging:
"I bought it in order to get data from my daily life and my exercises, consider the reviews of other buyers and in some cases said that the device malfunctioned, and thought that I was going to pass me, in effect the device was connected to the app on my phone only the first time you turned, after charging completely and never reconnected again, as I did my best, I load again, uninstall and reinstall the app and nothing happens, my cell is a Sansung Note 3 and connects perfectly with all my Bluetooth devices."
_
"I've had this product for two months and it's having a problem charging and the numbers are fading"

"At first it worked very well, but now after a couple months of use it has broken by the battery charge part and will not charge."

_
"Great fit, great design, first charge lasted a month"

Connection

Connection:
"However with that being said I still find I have problems with it staying connected all the time, and once it disconnects I lose the ability to see updates on my wrist (which is an awesome feature by the way)."
_
"I am unable to get it to connect to my IPhone 4."
_
"The coord is relatively short and it's hard to tell if it's connected (it uses magnets) Also, you have to take off the Jarv to charge it."
_
"This product also looks like it is used, one piece is missing that is supposed to connect it to the computer."
_
"Unfortunately after getting the item and trying to connect it I find that while it may work with that app (remains to be seen) it has to have the i-GotU Life app first and for some reason this app is not available."
_
"I checked the charger connection, all looked great...charged for 4 hrs- nothing."
_
"While the magnetic charger connection is a great idea, it's only good if it works."
_
"Fast delivery, excellent connection with iPhone"
_
"The blue tooth connection to your phone is nice as well."
_
"Recently purchased another tracker and it worked well right out of the box, connected to the company's and began tracking information."

Sleep

Sleep:
"It literally just counts steps and shows you uv index...any phone made in the past 15 years can do that...ordered one; sleep tracking didn't work - had it replaced - it's a problem with the entire product line."
_
"counts steps while you sleep which is kinda weird but it is attached to your wrist and you move as you sleep."
_
"I bought this device off of Groupon it's very comfortable the battery seems to last okay the only problem I would say is that it didn't track my sleep without me messing around with the settings other than that it's a solid piece of equipment the app is free but it's pretty solid piece of equipment."
_
"I've had the same issue with my bracelet not being accurate on steps and sleep count."
_
"It's a little confusing because to set your sleep time it is under Device auto sleep which threw me because I thought it was to set my watch to sleep not set the time I expected me to be asleep."
_
"Sleep monitoring lacks precision and accuracy."
_
"The sleep tracker seems accurate in that, the days I feel tired it shows a poor night's sleep and the days I feel rested it reflects that."
_
"The sleep tracker seems to be pretty good but the calories burned are a bit off."
_
"Its great love the sleep function but I think the step mode is off a little"
_
"I am not sure the sleep mode is completely accurate but it does give me an idea of what I am sleeping."

Sync

Sync:
"Also the app is terrible, it's so basic and doesn't sync with any of my other apps like myfitnesspal."
_
"I purchased 4, however one of them has not been able to sync."
_
"It synced easily to my iPhone and gave me notifications right on my wrist as well as phone numbers of calls I received."
_
"I would recommend that you sync it at least once a day."
_
"It syncs well with my phone and the battery life has been great!"
_
"Also, synching the item was very hard as I actually laid the item on the phone as well as very close to it and it still could not find it to sync."
_
"Could not get sleep to sync with the item although the app suggested was pretty good."

Track:
"I bought this device off of Groupon it's very comfortable the battery seems to last okay the only problem I would say is that it didn't track my sleep without me messing around with the settings other than that it's a solid piece of equipment the app is free but it's pretty solid piece of equipment."
_
"I like being able to track results on my phone instead of having to use the computer."
_
"Love this device keeps me on track!"
_
"It has a great battery life, very comfortable wrist band, and does what it is advertised to do; track steps, sleep length and quality, burned calories and summarizes your daily activity."
_
"it keeps very good track of my steps, and once I downloaded the mobile app I'm finding it very easy to see how I'm doing."
_
"so overall this is a great deal if you want to track your steps , sleep and receive a nudge to get up and walk around."

Tracking

Tracking:
"Tracker does not work well."
_
"It literally just counts steps and shows you uv index...any phone made in the past 15 years can do that...ordered one; sleep tracking didn't work - had it replaced - it's a problem with the entire product line."
_
"All attempts to reset the tracker were to no avail."
_
"What I do not like about it is that the steps that are being tracked are not accurate."
_
"The only downside we've experienced with the actual activity tracking is how easy the device is fooled into thinking arm motion is leg motion."
_
"But, I work out at least 4 times a week and the Life app didn't do a good job of tracking my workouts."
_
"Great little fitness tracker!"
_
"The notifications worked great, the tracking and the app did great."
_
"I've had the tracker for months and love it."
