As many have said before, it seems to me that it would be a pointless purchase, and a great source of troubles if you eventually want to sell it.
But I understand what may have attracted you with this instrument, because you're at the point I was some 10 years ago, when I wanted to "go baroque" without knowing very well what I really wanted to play and so, I was in search of an "hybrid" or a "one size fits all" instrument. But, believe me, there is no such thing anywhere in the world !
So my advice is to go for a real baroque guitar (which may not be very more expensive than this pricey "fake" baroque) but before, and if you want to get more familiar with double-strings courses, you can just buy a cheap but good 8-strings ukulele (look for Baton Rouge T8) : it will allow you to play all the renaissance guitar repertoire without any modifications. Plus, the lowest course of a baroque guitar being re-entrant, you will be able to play a good deal of the baroque repertoire with minor adaptations (The Roberrt Strizich edition of De Visée in staff notation clearly shows that the actual lowest pitch in all those pieces is a low D). It will cost you less than 160 $ to know if the double-strings are OK for you, to play wonderful music, and to save money for a future, real, baroque guitar replica.
Hope this helps,
