Review:
5 buffers and 2 bonus ones.
To start 3 from the 5 keywords i give where wrong used for the backlinks, the web2.0's are not top but the price is low, after one week not one was indexed in google (takes one sec so i did myself) No use off keywords in site title, H1 etc etc and no use off keywords in subdomain.
Tier 2 i most useless becourse again wrong keywords used.
All in all it is get what you pay for, it is cheap but not expect so much.
Edit
One off the bonus site is already down, so i can not advise send your links to the bonus sites.
