And if you SEARCH TPF by the name of the seller, as well as search the name of the store, you will find many more threads/posts. There were too many results for me to link each one for you.
And you might also check w/ some of the girls on the LV Forum.
You can also check the seller's feedback at www.toolhaus.org.
I know a few pfers who have bought from this seller. To me, their items look authentic, but just post the auciton link in the LV's Auth This Thread, just to be on the safe side.
I noticed their prices are super high!
