I ordered this battery last week after searching for a replacement for the battery from my lenovo which wasn't holding much charge anymore. It was quite a bit lower price than other batteries on here, but I took the risk knowing I can return it if it didn't work right. I received it pretty quick which I was pretty happy about. When I put the battery in my laptop, it worked right away and was fully charged. I didn't have to do a charge-discharge cycle or anything... it just worked! Overall I think it's a great buy and I hope other companies can see how valuable it is to make these products hassle free like these worldcharge brand. Also, the packaging was pretty sturdy and easy to get into no plastic blister pack or anything.. Took me a total of 30 seconds and I had the battery out of the box and my laptop up and running. It seems to actually hold a longer charge than the original battery did when I first got the laptop, but I will have to use it more to see over the long run.
Not bad for the money.
The battery was dead when I opened the package. Luckily, it comes with a spare & a jewelers screwdriver to change the battery. The cutout in the foam-lined case is too large to hold the caliper snugly. The thumb-wheel wiggles too much, giving it a cheap feel. The instructions are very minimal and does not explain much, including how the caliper works when the user puts the battery in backwards. - Because it apparently works and has some different modes. HOWEVER, when you put the battery in correctly (a guessing game because there's NO markings) this caliper works nicely. "At the end of the day" this was a good buy.
