#EDIT:
Received a copy, tried the availability checker and the turbo, both work perfect and fast.
It's $12.50 for a lifetime copy, totally worth it!
Thanks OP, GLWS.
InstaGrab is a wonderful product, it's well worth the price for a lifetime membership + updates.
In my opinion it is TOO fast, I feel like I'm DDoSing Instagram haha, but it's very reliable.
