About the product:
I bought a replacement battery for my now obsolete mobile phone since I don't see why I should upgrade to a smart phone. This was the only place I could find it and I love the fact that when I charge my phone now it tells me I have an "Alien Battery" :)

About the product:
The batteries (one phone- one camera- and one for a TomTom navigator are working OK. Time will show if they will keep the capacity as they age.

Quality and safety
