For me the answer is a resounding yes. It does add some bulk, but not like I thought it would. Honestly, I think it feels better in the hand than with the stock battery. Was told to expect 1.5x stock battery life, which seems to be spot-on after a week of use. Only bummer is missing the kickstand feature of the shell/holster combo, which the device no longer fits.
Like you, I was worried about the added bulk. But they took one out of the box & let me put the cover on my phone to get a feel for it, & that convinced me. Probably not a bad idea to try before you buy, if your Verizon folks are as accomodating.
Btw, I'm speaking of the oem 2150 mah battery & cover. My apologies if you were thinking of one of the other available extended batteries.
