Compact Steppers and Ellipticals?

I'm currently considering/reading reviews on the Sunny Health and Fitness Twister Stepper with Resistance bands and the Stamina 55-1610 InMotion E1000 Elliptical Trainer Has anyone ever tried these products? Are they effective? Are they quiet. I would like to be able to use it in my room while my daughter sleeps, and her room is right next door to mine.

Here are links for both of them https://www.amazon.com/gp/aw/d/B0016BUR7I/ref=aw_wl_ov_dp_1_3?colid=2AXLEUZ3IDTHW&coliid=I7A7ZCXM3TPWP&vs=1 https://www.amazon.com/gp/aw/d/B000VICRO8/ref=mp_s_a_1_1?qid=1438873148&sr=8-1&pi=AC_SY200_QL40&keywords=stamina+in-motion+elliptical+trainer&dpPl=1&dpID=51k5Z+YMtSL&ref=plSrch
