Not much to say about a battery..but I will attempt to make an effort ;-)The pros:1) Price!2) Performance...This battery charges perfectly in the OEM Sony charger. +1 for generic!The battery holds a very good charge....now, it has been my experience that ZERO 3rd party(generic) batteries have EVER worked, or held a charge as long as, the OEM supplied/version battery's do.But, for a fraction of the price, you kinda need to EXPECT a fraction of the performance.I have found that MOST of the GOOD generic batteries(i.e. the batteries that fall between dirt cheap(crap!) and OEM prices..) typically perform about 2/3 or more compared to the OEM. Meaning, you can get 2/3 the shots, 2/3 the discharge rate, etc.You get like 60-70%(probably conservative for some brands) performance compared to the OEM battery.And for my 'pocket' or 'travel VERY light' camera, I dont care if it is "only" 60% performance. It works.Now, it has also been my experience that third party batteries DIE muuuuuuch quicker than OEM ones will.I have not "killed" one of these yet, so cannot compare this one's overall life span performance, yet...I will amend this review if the battery does NOT perform well over time. If no update, then this battery is still clicking away inside my camera! ;-)Oh, if you have 'pros', you need 'cons', right? sorry.The Cons:....would like higher mAh rating..? like 1800+Cheers!Brent

I purchased this battery for my SLT-A37, it works just fine. I have heard of issues using aftermarket batteries in various cameras but I have not experienced any negative issues that diminish the functionality of the camera. The camera displays the percentage of battery left as it should. I have not done any testing to determine if I get the same amount of shots per charge or anything like that, but I haven't felt as though the battery drained more than it should in comparison to the OEM one. For the price this seems to be a good value.

This product is a complete waste of time and money. I thought that I could save some money going with a generic product, after all. . . a battery is a battery right?. WRONG. This battery failed to hold a charge on the first attempt. I was headed for vacation the next day and found myself out of luck and missing opportunities to take pictures because my back-up battery was worthless.

The best Sony NP-FW50 Battery 1500mAh you can get for the price. Charged the battery, inserted and the camera recognized it right away.Update 07/12/2015It is the best product you can get for the price.I lost the battery charger of my Sony α NEX-C3, so in the process of buying the new charger, I decided to buy a new battery, and a 32 GB Sony memory Card, to complete my camera kit.Very satisfied with the new battery charger. It works the same as the original I had, but is much better, because of the extra option to charge in the car from a cigarette lighter.The new extra battery I bought is great, the capacity is greater than original I got with the camera, and now with 3 batteries and, the charging from car option, my camera can make endless pictures, without fear to run off power, especially in wedding ceremonies (of closed relatives). It was obvious that I did more interesting photos, then the hired professionals, because I did twice more photos, and had the option to select the best.The new Sony 32GB SHDHC Class 10 is the best I could get for the price, and works as well as original 16GB that was included with the new camera, I have bought 5 years ago.I had to wait for a month, before giving the feed back, to make sure, to be able to give a unbiased, trust worthy information, that can help new buyers. And I got all, free shipping from Amazon.

Bought this battery as a back up to the one that came with my camera. Worked well for a while, then stopped holding a charge. I reached out to the company and they are sending a replacement. Unless you want to spend more, you shouldn't expect this one to be just as good as the Sony brand. But their customer service impressed me and that is something to consider when buying any product. For the price, you can't go wrong!

UPDATE on December 30, 2013: This battery is now dead. It's been in the wall charger, which indicates that it's fully charged. But when I put it into my NEX-6 camera, the camera will not power on. The camera does power on when the original Sony brand battery is inserted. I should have stuck with my preference for OEM brand batteries instead of buying this one. Now this one is destined for the recycling center, and I'll be purchasing a genuine Sony brand battery to replace it.ORIGINAL REVIEW: I generally buy the OEM brand battery for my cameras, but this time I went for the less expensive brand for my new NEX-6. This battery has charged up just fine and works just fine in my NEX-6, including the camera's displaying the charge percentage of the battery. This off-brand battery may not go as long on a charge, and it may not have as many charge/discharge cycles in its lifetime, as the Sony branded battery does. Well, at the price they're asking for it, the Sony brand battery should be darn near immortal. I'll probably buy another one of these off-brand batteries before I take my camera traveling. With 2 of these plus the OEM battery, I should have enough battery power on hand.

This battery fits my NEX-5R pretty snug, similar size with the OEM Sony battery. External charger is great since Sony's more expensive brand can cost 3x as much. Although its only been charged twice, I notice that when powered off, the battery still discharges ~1% over the course of a few days while in the camera. With the Sony branded battery, I don't see any type of discharge. For the price, non-OEM, that comes with a wall and car charger, can't ask for anything more. It is a good addition to have an extra battery as these cameras use so a lot of power.
