    Bought for my led torch, dispatched the same day and with my two days later. Great price, free delivery and top quality item. Let's my torch reach its full potential.

    Happy with the service and the batteries are excellent and at a great price will be happy for more


    Purchased through eBay and was thoroughly impressed. Having bought a 40T previously through a different vendor, i proceeded to compare them! The Samsung 40T was better offering up to 25% more battery life!! Outstanding. Finally i would like to say how clever it is printing the sellers details on the battery. No mistaking which is which. Don't know if this is the case with 18650's, will have to order some & find out!!
