Battery Replacement for HP Envy Delivery time was reasonable. Fit perfectly. Just installed. Found great video directions on install on Youtube. Computer says it is "best battery life and best performance". Hope I get long life from it.

Avoid at all cost. Battery didn't even lasted for a week. The battery isn't even a geniune manufactured battery. They actually mask it up with tape to prevent themselves from being sued. I have this odd 0% bug where I can't turn off nor work on my laptop without having it being plug in. I tried every geek tricks on the web but nothing fixed. Also, my device detects random unknown trojan virus's that wasn't even there to begin with. Shipping took way to long, approximately more than 3 weeks it took for me. Not worth the money, learned my lesson.

Battery was reliable and correct for my machine The product I got was an exact match, and two weeks in has so far worked great! The battery life has been as expected, and it's brought my computer performance back to what it was before my battery started to fail. My only complaint was the stressful shipping. They use DHL, and the battery took about 10 days to reach me with seldom updates. However, I did get it and the day of updates were accurate using USPS so overall, good experience! I recommend this place, especially because I saved a ton of money and time being able to do the replacement myself.

Lenovo Think Pad They had the battery for my computer, which is older and it was shipped promptly and delivered on time. It was relatively easy to install the battery once I got over the fear of opening my laptop and messing things up. The screw drivers that came with the battery were helpful.

HP Spectre x360 Shipping took 10 days instead of the 3 to 7 as advertised. The battery seems OK but I ended up having to twist the connector around opposite of how it comes in order to have the laptop recognize the battery. Hopefully it will last. Haven't tested yet how long it will go not being plugged in.
