Anyone try the Seidio batteries?

Okay, today was the first time where by 8:00 am I was at half bars from using GPS to get to an appointment! So I was stressing all day but luckily, I was able to get through with my phone working until 5:30 pm.

So, I've been looking at aftermarket batteries to get longer daily use out of my TP and Seidio is a name I trust. They sell two batteries, one that they say adds 10% (1500)

and the other 50% (2000).

Has anyone tried these? It seems the 10% is not even worth it but since it seems the same size as stock, it won't add any bulk to the phone. The 2000 that adds 50% life seems like a no-brainer but it disfigures the phone so much. I'm wondering if it's worth the investment.

Those of you who have it, please chime in.

TIA
