Great product
These are better than the batteries that I've been buying from my local vape store, they last a lot longer. Many thanksDo not charge
They were delivered quickly. Although they were easy to fit into the video doorball, they are not charging. I have tried swapping them over yet it is still the same. So not very happy as they are quite priceyValue for money
Top price for four batteries. fairly quick delivery time. Well packaged. Unfortunately, no case - as was advertised. Would buy again if the order included the case!Samsung batteries
These are an excellent buy, I bought them for my vape. The batteries hold their charge longer than previous ones I have triedGreat product Great price
Really happy with the purchase. Cheaper than anywhere else that I could find and quick delivery too. What more can one ask for?!Good value
Very good value a very fast delivery time and service I would very much like to to recommend the sellerMisleading
I got more that I bargained for but the picture is misleading I thought it was coming with a box to place the batteries but I was wrong! I got 3 batteries instead like I said more than I bargained for but still. When it comes to the batteries well what can I say! They do the jobBatteries
The batteries do there job. Fast delivery and product works. The product image did show some sort of clear box too, but that wasn’t delivered but it wasn’t needed.Great
