This seller operated as having a UK base as 'uk. Laptobatterylife' & 'laptopbatterylife' offered a 12-month warranty on his product & a 18-month subject to a fee which I paid. Merely 4 months down the line my Apple magsafe 45w power adaptor stopped working, the seller did not respond to my email and there's no longer an online presence of his company (under the same name at least). Fortunately since the purchase occurred in the allowed 180 days I was able to contact Paypal who will force the seller to make a refund but this only after I send the unit all the way to China!. Avoid this seller at all costs
