It's easy to give a good review when you have received your product or at least a reply to your email. I suspect all the people that have given Sterlingtek a good review had no problems.  
I'm a seasoned online buyer and I am used to track my order when I buy something. I'm used to receiving notifications when a product ships with a tracking nr. I've received no communication besides the one when I ordered. Two months later and I still have not received what I ordered. I've mailed them a few times asking for a tracking nr but they NEVER reply. Do not buy from them. You might be one of the unlucky ones with a problem and you won't get any service.

I ordered a Nikon battery (EN-EL9)from Sterlingtek and it took weeks before I got it. It worked fine for a few months and then it suddenly died while I was taking some family photos. This was my backup battery, BIG mistake ... Also, they clearly advertise a one year warranty ( http://sterlingtek.com/nieneqba1.html ), but they wont respond when you try to contact them.  
Do not buy from them unless you want to waste your money and time with their poor products.  
 

I live in South Africa. I ordered 2 Canon equivalent batteries for my EOS300D. Paid via Paypal. The equivalent battery in SA costs about US$100.00. I received 2 for US$32.97 delivered to SA. They arrived in less than 2 weeks. I have and will in future recommend Sterlingtek to all my friends and colleagues.

The shopping and checkout experience was fine, my order was being shipped to a P.O. box so I didn’t expect a tracking number, however I did expect an email letting me know that it had shipped. I had placed my order on Wed. and by Thursday all I had received was an email confirming my order. I emailed them and got a reply by that afternoon that they had shipped the same day I had ordered it. the package had already arrived in my box! Very efficient shipping, good customer support, they even gave me the tracking number (USPS doesn’t track packages very well... however it did show my package got put in the mail). I am very pleased with the product. It is exactly what I was expecting, third party batteries. The color is more green then the picture on the website… but I couldn’t care less LOL.  
 
Great merchant, I will do business with them again!  

Ordered 2 BP511 batteries from them on Saturday. Received them Tuesday. Very fast service. Would have been a better experience if they emailed me when they shipped it, however. Great experience nonetheless. Hopefully the bad batches I've heard them have were finally replaced by now. Batteries + charger seem to work well for the time being.

Great products at awesome prices. Power supply eventually failed and support was extremely helpful and fast at replacing it. Sterlingtek is by far my favorite place for digital camera and laptop batteries as well as laptop power supplies. Fantastic retailer!

I ordered two batteries for my Canon 40d - Prices are excellent. I recieved a confirmation email right away, and recieved my shipment in 3 business days. All of the positive reviews that I've read have proven to be true in my experience. Excellent company - Would buy from again!

Purchased 3 batteries and 1 charger and received them within a reasonable amount of time. Batteries are excellent working just as good as factory batteries. For the price of the 3, I could have just bought a single factory battery. I would buy from them again.

I ordered a couple of camera batteries as well as some AA 2700mah batteries. Shortly after I placed the order I received an email informing me that the "2400mah AA batteries" were on backorder, and that I could cancel that part of the order so that the rest of my order could ship. BTW, it is not a mistype, I did order 2700mah batteries, and Sterlingtek did refer to them in the email as 2400mah batteries. I emailed them back asking them to cancel that part of the order. The next day I received a confirmation that the AA battery part of the order was indeed canceled and that the rest of the order would ship. I received the rest of the order on the 2/4. I noticed that I had not been reimbersed for the AA batteries and sent them an email to that regard. I received a response telling me that the person responsible for the refunds would take care of it in the next few days. Three weeks later, no refund, so I emailed them once again. The response took several days and I was told that my order had shipped and to contact the shipping company. Talk about total incompetance, the person, Cindy, didn't even bother to notice that only part of the order had shipped!

Ordered two NB-2LH rated as 1700 mah. Knew full well they couldn't be that high, but for the price, who cares, it was worth it.  
 
They send ones that are listed as 1000 and after repeated questioning (5 emails) they respond and say that they sometimes use "replacement products".  
 
It's still a good deal, but remember that they are not what is advertised.

This is the second time I have purchased from SterlingTek. I will buy from them again when I need more batteries. Excellent company!

After reading online recommendations, I ordered a BP-511 replacement battery for my Canon 20D. It arrived in three days! It's much cheaper than Canon batteries, and it seems to fit and work just like the original, though I don't know how many shots it will last yet.

I've had great experiences with Sterlingtek in the past. While they're batteries might not last as long as genuine canon batteries, they're a heck of a lot cheaper and well worth it. This time, I ordered some extra camcorder batteries for a trip. I needed them delivered by a Friday and selected the proper shipping option. To make sure I would receive the batteries on time, I e-mailed customer service to verify the shipping information and get a tracking number. The representative was very helpful. To my surprise, the package arrived the next day, even though I selected 2-day shipping.

I paid a little bit extra for express shipping on two Canon compatible batteries, and they came as quickly as advertised. The replacement compatible batteries look just fine, at a price much less than half that of original Canon batteries. I would do business with them again.

ordered two batteries for my Canon 30D. They didn't fit, so I sent them back (from the Netherlands). Within one week I got two new batteries, that fitted just fine. No extra charge for First Class delivery! Excellent after sale service!!
