I needed a replacement since my Wii did not read any games at all, tried to clean the lens etc. But nothing worked, so I bought this! I am satisfied.
I would recommend this since, as I said, it does its job by reading my games and allows me to play again, but its very noisy.
But anyway.. Its cheaper and even more cheaper and less time consuming, than sending the whole wii in to Nintendo service center for repair, where it is possible to loose saved data etc. etc.
