Almost as good as the standard Cu-poche Saber with the cloth robe (the robe was awesome).
This Alter version has elbows and knees (which Nendoroids only started adding recently). The magnetic base is another awesome idea because you don't need the included arm to steady the figure, unless you want a flying/jumping pose.
Cu-poche are about 11cm, slightly bigger compared to Nendos which are mostly under 10cm.
