Best of a bad lot?

Am looking at these three phones and am wondering are they worth buying in? The first is supposed to be very similar to the S4
http://www.amazon.co.uk/Quad-Core-smart-phone-1280x720-resolution-supported/dp/B00CDJW76Q/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=GCBAIVIMHFMX&coliid=I38E9G7BIIXDBH

The second is also similar to the S4 http://www.amazon.co.uk/S7189-MTK6589-Android-Smartphone-UNLOCKED/dp/B00BG8F9G0/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=GCBAIVIMHFMX&coliid=I2EODDMOVS2WL8

The third choice I have is just and s3 mini...

Are these phones worth it and can they be used with an Irish sm card?
Why are they so cheap compared to the higher end phones even though they have similar specs... does this mean that they are less reliable?

EDIT: Also this http://www.amazon.co.uk/gp/product/B00CE5HAIO/ref=s9_simh_gw_p23_d0_i4?pf_rd_m=A3P5ROKL5A1OLE&pf_rd_s=center-4&pf_rd_r=1YS393MP414VWXY8DKZ7&pf_rd_t=101&pf_rd_p=430256647&pf_rd_i=468294

Feedback will be appreciated because I am ****e with technology

These phones are cheap because they do not have a set brand, and are made in China and other countries.

This goes back to the age-old debate: some people say that these knockoffs are fantastic, while some say that they are inferior and of a lesser build quality. It really depends on your stance.


If I was going for any of these, I'd go for the 5.5inch Note imitation. And I'm a Samsung Galaxy Note II owner.
I would go for a phone that was big and had a good battery... which the imitation apparently has.
