I like that it gives you suggestions of different keywords depending upon your niche/product category as well as other factors such as competition etc which helps in getting better results faster than if one were just trying random words out! It's also easy enough so even newbies can use this without much hassle or difficulty at all. There are some things i dislike about ASINKEY but they're not really big issues - maybe minor ones only (like sometimes when searching multiple terms there will be duplicate suggested searches). If used correctly then its great because once set up properly with good data sources from trusted sites / tools; plus having an understanding how search engines work would make using any SEO software easier anyway :) So far no major problems have come across while working through my own research & testing process however do keep checking back periodically due to constant changes within Google themselves meaning anything could.
