Query: Battery does not hold charge after 10 uses and 1 month!

Bought it for my wife as a x-mas gift. Worked "ok" at first, although it is difficult to get it attached/started. We fully charged it in the cradle for ~36 hours then it only lasted about 5 cans in one week of use. Recharged it and still only got about 5 cans. The third time it did not even open one can. We are now trying to find the receipt and return it! Sounds like our experience is not unusal...
