The only time I got burned with a GIT bottle (and I've owned 4 or 5), was when I bought a bottle at an independent perfume shop that was in a now defunct mall in Myrtle Beach, SC. It was obviously old and past its' prime.
All my bottles purchased from Internet e-tailers have been fine. Particularly Scentiments.com, they're the best.
I'm wearing Bond No. 9 Chez Bond today. VERRRYYY similar to GIT. I think I prefer GIT, but it's close.
