Great power supply, I've had it in my PC for 2 years so far and it works awesomely. Runs perfectly, voltage levels are all okay. I'm a heavy gamer and am on my computer all day and this hasn't given me a problem. Love it, great investment.

So far there has been no issue with these batteries. They charged properly, I've fully discharged and recharged one and got a few hours of 10 second timelapse from a single charge.

I was skeptical about these batteries but so far I am pleasantly surprised! I have purchased replacement batteries for my Porter Cable Drill and Saw kit several times and none of these products lasted for more than a year. You could tell within a short period of time that the batteries were no  longer holding a charge well. However, with these batteries I have noticed they hold a charge much longer. The most notable time is when the temperatures outside are much colder. The other batteries I had were of no use at all within about 15 minutes of use. These batteries are still working well even during the cold weather we had. I haven't had them a year yet. So, I may do a followup review after some time has passed to see it they will last a bit longer. It seems they are doing better than the previous brands I purchased. But for now, I am happy with these batteries!

I took these batteries, along with the original battery for the Sony dsc-rx100, into the Grand Canyon for 6 days of backpacking, and I only needed the original and one extra... these replacements lasted for pretty much the same duration as the original battery, and are still going strong. Awesome! Other reviews have reported inaccuracies with the battery life monitors in their cameras with the replacement batteries, but thus far I have not had any issues (my camera has given me a fairly accurate battery level readout with these batteries). Additionally, the charger works quickly with both these batteries and the original for the camera.

I have been using these for several monthes now and these are absolutely wonderful batteries.
I do not use them heavily so they need to last for a longer period of time; and they do. I put a set in my camera in October (before a vacation) and did not change until 12/25/09(just because I didn't want them to go out during Christmas pictures). I had taken about 120 pictures at that point and they were still going.
I highly recommend this brand over the two major name brand rechargables (no contest).

We've been using this charger consistently for several months now and have no issues with it.  It charges, it hasn't failed, it doesn't overheat.  What more could I want from this?  :)

Works well, no problems in the first 6 months of use, just hoping my luck with longevity holds up.

I've had this battery for a while now and have had no problems whatsoever. It seems like a good battery as far as I can tell.

Good product, they have held up pretty well and lasted at least 3 months now which is saying something from my experience. Decent battery life still too.

No problems so far, been using it 7 months.

I replaced the batteries in all five of my Uniden phones with these several years ago (figured it was pointless to submit a review as soon as they arrived), and I can say they've held up at least as well as the originals so far. Glad to find a quality replacement battery for once. I hope the current batch are as good as they were when I bought these.

Has been working without any problems. I tried a few other brands before this one and they all seem to die after a couple months. This one has outlasted all of the others.
