I run four businesses from home. It became difficult operating the four off two laptops. I purchased two Lenovo Thinkcentre's. They do not work with bluetooth technologies.The tower doesn't have bluetooth capability at all, so unable to download drivers to get bluetooth.Looking over the product details, it doesn't mention bluetooth nor lists its lack of bluetooth. I believe that this was imperative information that the seller's product description should not have left out.Was able to submit request for return and full refund.If you have no need to use bluetooth, the tower holds up in other areas.
