For those who are experiencing ED, andSons provided a convenient way for consumers to consult and purchase via online, so it saves lots of trouble for consumers to pay a visit to physical clinics. I am overall satisfied with the services after 2 times purchases with andSons. The only thing that bothers me is about the parcel tracking number. 1st purchased, I asked for it then only provided for me. 2nd purchased, cs support said I "will" receive the tracking number via email, but not at all. Waited until I kept on asking for it, then cs support replied me that it has been delivered to my address.......forcing me to rush home and collect it without letting my wife to discover it.........I believe this can be arranged properly for my next purchase.....
