I wish i would have read the reveiws sooner, i needed a Perc controller battery for a dell server real fast, phoned dell and they said you are best to buy from an online store as it is an old server. So i surf the web, filter google by UK sites only, choose a UK site "Laptops-adapter.co.uk" and pick the battery (this site was the only one advertising as a genuine Dell part), pay by paypal, then a few hours later get an email to say it has been posted from HONG KONG! Suffice to say that was no good to me as i needed the perc battery ASAP, so ended up having to buy another one to get my server issue fixed. Luckily i paid by paypal so have started a dispute to see if they can help get my money back. Its a nightmare i thought only exsisted on Ebay, now they are doing it via. co.uk address too!
