I bought this product based on the reviews, as always with all products from amazon. This product was suposed to allow to connect different peripherals to the docking stations and not to the the laptop directly, that is the difference between this model and the previous model. Well, all those functionalities worked for just few days after I installed the software that comes in a CD to the laptops, after few days the USB ports didnt work any more, I tried deleting and reinstalling the software and nothing... So I think it was a hardware damage in the docking stations. I couldnt process a product return because I was leaving the country next week so I didnt have time to wait for a new item... It is suposed to work from the fist time...Based on other reviews the product is good, I guess I didnt have luck with the item I received and couldnt change it... So, it didnt work for me and I cannot recommend it at all. Expensive product to be only a base for the laptop.
