I bought these twice (3 each time) over the past year or so. I've been using them in a number of portable radios. I've noticed two things:
1) In the radio I use most, an Eton E5, which has multiple timers and which I often have running many hours overnight, I am continually having to switch the batteries at least once a week and more often twice a week. I'm guessing that this radio has far more current drain than the others, so it may not qualify as a "low-drain" device and is more like the high-drain items like a digital camera, for which these batteries are specifically NOT recommended. In other, less-used radios, they last a reasonably long time before losing power.
2) When I charge them, the charger stops blinking after a day or so of charging, but if I rearrange the batteries in the charger, so that each charging position gets a different battery cell, it resumes blinking (& charging). Only after a couple days will the LEDs remain steadily-lit no matter how I arrange the cells, and then I assume they are fully charged. I can measure the batteries with an analog Simpson battery-charge meter (pro test equipment back from the 1950's) and they will read 95% when fully charged. Perhaps the people who say these are "lousy" batteries don't go through this process of rearranging and multi-step recharging, and thus never fully recharge them? Or maybe they're really just "lousy" -- I'm not defending their quality. :-)
