I would be... extremely cautious about ordering one. Mainly because Nintendo, without doubt, is ready and waiting to file lawsuits. For devices like this, there is a real possibility of having all customers revealed to Nintendo during the litigation.

Edit: For those who say it isn’t illegal, sure. Dumping ROMs by itself is not illegal (like from an NES or Genesis). Circumventing copy protection, however, is quite possibly illegal. The DMCA in particular has many sections on “circumvention devices.”

This will not allow you to dump saves from an unhacked switch, it only dumps physical games. All saves are stored on the console's internal memory.
