A large percentage of these are on duplicate IPs. Add the fact that they are instant approval and you don't have a much of formula for quality.
I'd recommend sticking with a handful of reputable directories and focusing your SEO energies elsewhere. Outside of the top few reputable directories, you won't get much link juice or traffic from them.
Ezine remains one of the best places to get a quality backlink. Just make sure you have a quality article and avoid anything spammy. Also be sure to build some backlinks to your Ezine article, as it is easy to build PageRank and link juice there.
for quality backlink always submit your website link in manual approval directories although it is not instant , but it gives more sucess in gaining link juice
