I bought 3 Pen DVR Camera a 4GB & two 8GB. They all stop working within the first couple weeks. DO NOT ORDER THIS PRODUCT... It is does not record more then 5 minutes at a time. The ads state it will record "up to" two hours straight. Now I know what the up to is for. Honestly this is a very cheap product that breaks way to easy. I was so careful with them and still broke. They only worked the first time I tested them and then a couple weeks later they did not work at all. I'm not the only who has been cheated by chinese sellers on ebay selling cheap inferior electronic junk. If your smart you will stay away from this product...
