Battery works perfectly. I think it holds a longer charge than the one my phone came with. My only regret about buying it was the lack of NFC antenna. To be fair, i barely used google wallet anyway because most stores had a broken reader.

The battery is perfect back to long run times on battery, works like a charm.

Had this vacuum for quite a few years. Original battery never seemed to hold a charge so it sat unused. Was going to toss out but decided to try to replace battery first. This battery fit perfectly and does hold a charge for a lot longer than original battery. I get about 10+ minutes continuous use. I have been using the vacuum for spot cleaning (1 to 3 minutes at a time) now to test and so far it has held charge very well. Am glad I decided to try this before getting rid of the vacuum.

I've been using the battery for about a week now. It is definitely holding a better charge than my original Samsung battery that is about 2 years old now!

This battery was a perfect fit in my laptop! It has been working great for a week now and holding a charge for much longer than my four year old battery. This was money well spent to be able to use my old laptop for a longer time without having to plug it in.

It's a great battery for the price.  Holds a charge for at least 2 hours, maybe more.

I just placed the battery into my laptop and it fits perfectly. It came charged at 70% and with me using a lot of bandwidth it's showing two hours of battery life. First impression: very pleased.

I got the battery days before it was scheduled to arrive which was fantastic! It works great too. So far it seems to hold a charge just as long as my Apple battery did when I first received my computer.

I carry this in my briefcase to power my phone and Lenovo Ideapad when I deplete their batteries.  One time on a road trip my cell drained on me and I did not have a power source in my truck, but I had this battery.  I hooked up my cell to it and placed this battery on my dash in the sun, which allowed this battery to simultaneously charge itself while also powering my phone.  Neat.

I do recommend this unit.  It works perfectly, and has ridden around in my briefcase for months with no damage.  My briefcase is a soft-sided 511 tactical bag with some heavier items in it, and this plastic battery case has held up just fine.  A good deal.

UPDATE - Sept. 2016 and it still works perfectly.

I have had the batteries for a short time.  But so far, both have performed perfectly.  Love the additional capacity !  A full charge seems to last quite a long time .  .  .

Received battery about a week and a half ago and it has performed flawlessly. This batter replaced bad battery that would last about 10 minutes being unplugged. Now I can use the laptop for 4-5 hours after a full charge. Fast shipping and great packaging. Thank you so much.

I ordered 2 of these batteries but I have currently only used one of them. So far I am completely satisfied with its performance. It is a long lasting battery and it works just like an original Samsung.

I am very pleased with this purchase.  It works perfectly.  The battery lasts alot longer than the original every did.  I wish that I would have replaced it sooner with this battery.
