I am member of Seventymm more than a year now.... and I must admit that they have one of the best movie collection available across all movie rental libraries which I used. Also the service is good, I get movies on time whenever I order.
At times, yes, when there is an issue of availability of a particular movie which I want to order, but that is the case with all movie libraries, but most of the time I get the movie I want. Also the staff is very corporative and genuinely tries to help and resolve if there are any issues. so if want to watch lot of good movies at your convenience, I recommend this is the best solution for the same.
