100% Legit, the quality of bots on this site are impeccable and definitely unrivaled.
However, as stated earlier, a number of their bots aren't regularly updated and some aren't up to par as others, but this site does have the best Sorc Garden, PuroPuro, Runecrafting, and general skilling bots.
I personally own auth codes to over 10 of their bots, and I must say each and every one ceases to amaze me at it's performance.
