License Tier 3 was promised before with BYOK for future models, but it was removed and limited to almost silly old models with illogical reasons even when they are called logically. Unethical business. I recommend to stay away. I selfom give a negative review on AS but unfortunately, for these guys, it is really disappointing. This is a product review and not a service review. So i won't even start with the interaction and service them provide.
