I can't criticise the batteries, I'm just charging them, I'll put them to use then. I can only rate them after a fairly long period of use.
However, I am very satisfied with your service, fast order processing and prompt replies to my queries when the first shipment did not arrive. You sent the second one, which I have received.Verified purchase
