It works well and has a USB port so you can charge your battery and other electronics at the same time. It takes several hours to fully charge and the LED display is very bright and shows the charging status. I am happy with this purchase. I would like to point out that I would not recommend this device if you have vision/hand problems when handling small objects, as the tiny metal protrusions have to line up perfectly with your battery connectors or it won't charge, the display will show 100% , but the battery won't charge if those little metal dots aren't lined up exactly. You also have to be careful, otherwise you can easily pull these small projections completely off the slideway. I found it easier to place the battery halfway into the sliding portion of the holder first, about an inch or so above the metal tabs so I could line up the connectors better. Then, when they are in the right place, just slide the battery all the way in. You may need to do this from time to time because sometimes they shift or when you need to charge different batteries.
