Sorta easy to give life back to 300 dollar smartwatch

Funciona correctamente, dura más de 48 horas, un poco complicado instalar.

I feel like it has everything but I can't seem to get the y screws out on the first try but the product itself seems fine

I've been in the market for a smartwatch for a while. I am very picky about the design and functionality. I love the look of the Samsung gear s3, just something about being able to spin the bezel reminds me about some of the watches I had when I was younger. So I was super stoked to find one one here on Amazon in the renewed section. Unfortunately this is an older model and was in acceptable condition but a steal at just 36.00. I noticed that the battery had a hard time keeping a charge and it would die within a few hours. Looking for accessories I found this replacement battery. It was pretty cheap and came with the tools to change it. It was not too difficult and took about 20 minutes start to finish to change. The hardest part for me was getting the back off without damaging the wires. Then putting it back together correctly. I would recommend taking some pictures before and during the process just to make it easier putting it back together. There is nothing solder it all just snapped back together easily. Put it on the charger and now it works better then ever and being 520ma the battery last almost twice as long. The only additional tools I use was a flat head screwdriver to gently pry the back off and a magnifying glass to be able to see the wire connections better. So now I'm into my watch for about 50bucks and absolutely love it.

Terrible instructions. Battery is different from the one in the watch. Unable to remove old battery.

works great , easy to install

The pry tools are garbage and the screwdrivers were pretty awful as well, felt like I was stripping the screw almost immediately. Ended up using my own precision set to get the watch open. The battery extraction tool was helpful in removing and reseating the battery connections and the battery worked great until I traded in the watch.

This battery exactly replaced the original in my Samsung Gear watch. Now lasts at least 3 days. The installation is a little tricky but a few good videos on YouTube were helpful.The supplied screwdrivers worked well. The plastic tools for opening the case were useless.
