I must say long time ago when I was really naive I bought one wallet from him. He sells also 'hints', which are purely imagined I assume.
On the other hand, recently I paid him 15$ for "damaged paper wallet", because I was bored and I wanted to test myself. Something like 13 characters at the end were lost and partially damaged qr code was visible. I was able to decode manually part of QR code and combining it with WIF I restored the full key - which was of course for different address. But I had a fun and it was really interesting training in recovery
