AMAZON TOOK CARE OF THIS AND I AM COMPLETELY SATISFIED

Died after three months. Will not charge anymore.
**Updated review** I was contacted by the seller and a replacement battery was sent to me the following week.
I'm pleased with the customer service because they were prompt in resolving the issue = 5 star.
As far as product we are still testing it...  Stay tuned...
I originally bought two batteries, the other one still going strong.

After having this battery since November, it regularly only charges to 20%  In Batteryinfoview it shows my wear level to be 103%  My old battery lasts only 30 minutes due to leaving the laptop mostly charged non stop for 3 years, but is still holds 3000 mWh more than this new one...

For about the 1st month battey would last for a week. Now luck to get 3 day.

So far its a pretty good battery but I will revist in 3 months. Kit needs to add sticky strips to hold down battery. The old ones came up with the old battery. will give 5 stars if the battery is still performing as expected in 6 months

I've had the watch for less than 3 weeks and I'm already needing to get the battery replaced. Will cost me almost what I paid for the watch itself.

Purchased in November of 2012, however in January of 2016, the battery is almost dead and I need to reorder.  It barely lasted 3 years, let alone the 6-8 listed in the description and just missed the warranty window.

This is the 3rd one we have purchased.  The batteries only last about a year or less.  My wife loves the product but the battery life is the biggest problem.

Own 3. 2 out of 3 stopped working within a month or so. Replaced batteries, still junk. Waiting for the 3rd one to go bad.

Battery has been holding up for over 3 weeks now, charged my phone 3 times (from about 10% to 100%) and still has around 75% charge remaining.

See edit below:  Fits correctly and works well.
Life is good so far, can't tell the difference from factory one.
Looks to be high quality fit and finish.
EDIT after using it less than the three year warranty period
battery refuses to take a charge. Having a three year warranty listed
in discription is useless if there is no way to exercise that when the unit
will no longer function in any way. Was fine for about two years or so.
The OEM factory battery is still going strong so the camera and charger work.
are working correctly. Having a cheap spare was a bad idea.

The seller was MYBATTERYSUPPLIER. After I got batteries, I quickly installed in 2 watches. Guess what ?
Both drained in a little over 1 month. I think they are counterfeits.  I bought batteries 3 times from amazon in the last 12 months. This is the worst in 3.

After three months of use this watch started to slow down.  I got the battery replaced and the problem still continued.  Beware of buying this.

I realize that battery replacement are to be expected now.

The price was good, but the battery I got was dated/manufactured 02/28/2014.  I am a bit concerned about the battery being already 3-years old when I got it.  I hope it will last....

2of 3 batteries ordered failed within 2 months.  The third continued to work, but puffed up making the trackpad not click.
