Very Poor Quality Product from Game- Uniross Alkaline AAA Batteries

I bought a 4-pack of Uniross Alkaline AAA batteries about two weeks ago and I put two of the batteries in my new wireless mouse for my laptop last week. As I'm trying to turn my mouse on this morning I find that the batteries have run flat! I know it's the batteries as I put the remaining two in to test where the fault lies, but I honestly cannot believe the shocking quality of these batteries. The batteries literally lasted less than two weeks, I have Duracell batteries which I purchased for my alarm clock which have lasted over a year already!

Very unimpressed with the poor quality of this product.
