If you want to look at her stuff I would suggest her website
http://www.kaylakiss.com/ instead of buying clips because it gives access to whole slew of them, but be sure to cancel if you dont want to keep paying.
Her clips individually are expensive as hell unfortunately, probably because they are usually fairly long.
High quality for certain though, do recommend. Especially since she is still making transformation/expansion clips so checking in with a monthly subscription every so often is rewarding.
Honestly if her prices dropped to around $15 a month I would probably keep a steady subscription instead of popping in and out every 2-3 months.
