brought two 4-packs of these on vacation, had them run out on me faster than it seemed they should. do not seem better than energizer nor duracell. I bought some lithium energizers to use for my next trip. I was using them in a canon digital camera which works with normal alk batteries. bought these as a "get to $25" fill in purchase at amazon.

As a new parent and a electronics buff, I go through a lot of batteries. Whether it's D cells for the baby's swing or AAs for any of our 14 different remote controls, it seems like I'm always changing batteries on something. I do have some NiMH rechargeables, but these tend not to last long in higher drain devices. I tried out a few of these Monster AA alkalines in a sale from Amazon/Circuit City and so far, I'm impressed. My DVD-recorder remote (for a Panasonic DMRE100HS) was getting a little sluggish, even from just a few feet away. I popped the batteries into my tester and they looked like they were OK (90%), but on a whim, I tried a fresh pair of Monster AAs and suddenly I can control the DVD recorder from the far corner of the room with no problems! Also, in our son's Gymini playmat (which uses AAs for the music), I've had these Monsters in for weeks and they're still going strong. I can't say I've done any head-to-head comparisons against the "big two" (Duracell and Energizer), but from my experience so far, I'd say they're at least on par if not better than the coppertops and the bunnies. Try 'em... you'll like 'em.
