Is extended ebay battery better than stock

Just an update on the Hyperion. I got 13 hours today.... but with 5 hours screen time. That'll due and I'm still breaking it in.

I have to say that I'm interested in the Hyperion but I googled the company and they have a lot of negative press about them false advertising the power ratings of their batteries, including this one right here on AF:

That makes me a little tentative

I don't know. I've got great results with those one and the one in mys3(got over9 hours screen time with it). I've had problems with the task cheap ones though batteries though.

I've had the battery for most if this week now and here are my thoughts -
Battery purchased: Ebay 3800mah extended battery made in china
Price:$15 shipped

My daily phone usage: light screen use; 30-45 min of voice; 40-50 texts; 30-45 min of web browsing; 1hr pandora, 3hrs music from sdcard. Syncing 4 emails on push sync; facebook, facebook messenger, twitter, linkedin, hootsuite all running in background. Wifi, 4g, gps always on. I don't use airplane mode at night or anything like that, and I don't use Juice Defender, DS Battery Saver, or any other battery saving app.

Thoughts:
In short, worth it. My phone life might not be doubled but it is definitely longer. With the stock battery I would unplug it from the charger at 5:30 am and it be dead by 6:30pm. This battery seems to be making it to 10pm (end of the day for me) with 20+% remaining still.

Monday - the battery arrived around 11am and I just threw it in my phone, it came out of the box with 71% charge so I ran it for the day. It made it to the end of the day with around 25% remaining so I left it off the charger for the night... I wanted to completely kill it.
Tuesday -at 5:30am it had 4% remaining so I put it on the charger. Unfortunately the day didn't want me to get a proper full charge to start the day so I ended up on and off the charger all day with way above average use.
Wednesday - first full day... had above normal usage - 1.5hrs of Nav usage and 2+hrs of voice added to normal use. Battery seemed to drop at normal stock battery rate. By 6:30pm I was under 10%, but I kept it off the charger. I noticed it dropped down to 3% then went back up to 7%... finally died by 9pm, so I put it on the charger for the night. Flashed cm10b6 during charge time.
Thursday - second full day...above normal usage again, only mildly tho - 30min of nav added in. Made it to the end of the day with over 30% remaining, so I left it off the charger for the night.
Friday - woke up 4:30am and found lots of emails and texts received and a battery at 3%. Put it on the charger til 7:30am to get full charge. Above average use day again - 1.5hrs of wifi tethering, flashed twrp and created a backup, 2hrs of web browsing added to normal. By 11pm I had 20% battery left (remember it came off the charger 2hrs later than normal tho) so I just left it off the charger for the night.
Saturday - woke up at 7am, battery dead so its currently on the charger.

Afterthoughts: I thought I would hate the added thickness of the phone but it really doesn't bug me at all. This battery is great, especially for $15. The only thing I can figure (this is "the cup is half empty" thinking) is perhaps they have a crappy quality control system in place, so people will have higher chances of getting a bad battery... but so far I think everyone here that has gotten one likes it.
