[EX Q]: First off, it's a lap top with thyroid. Second..you cannot add anything to it as it's a closed, sealed system. Tech support is done in a foreign country by people who can barely speak the language. Finally, this ran perfectly for 13 months...then melted down. The price has come down from $1100. But now I'm stuck with amounts to an $1100 boat anchor.

[EX Q]: I want to thank the people at Sun Valley Tech for their excellent customer service. I bought a battery for my 12\" Mac powerbook in March, 2009. I ordered the wrong battery; it was entirely my mistake. But Sunvalley agreed to accept a return and instead of charging me a hefty re-stocking fee, they only charged me shipping plus 10% f the purchase price. I thought this was very nice as it was my mistake. My advice, check your details before ordering!
