I just bought this product for my previous computer passed away and I needed to recover my data on the hard drive. After an unsuccessful connection (abnormal heating of the components, I was scared, I thought I was going to burn the whole house ...) I have everything to reconnect all disconnected then and there it worked. So I was able to recover all my data without worries. Compared to other products of the same type, I think it is still worth its price. My brother had bought a lot cheaper and you see the difference; you receive it in a beautiful box (style mobile phone box) and the components are packed separately. Well of course it's made in china so it's make or break: either you come across something that works perfectly or you lose 20 euros ... In any case when it works it helps out well and I recommend this product which currently meets my expectations.
