PROS-Sound - Sound quality is really good for price. you could put the same, cheap, components together for 1/3rd the price. I plan on purchasing more to just have them haha. You can pop in a couple of in-ear monitors or shielded headphones, and have the PC select the Samson as the speaker. I have followed the instructions exact and nothing. I am not surprised that the seller has slashed the price on the trainer by nearly 50%. The box was poorly folded & taped together with nothing more than a hope and a prayer. The material is soft rubberish and feels comfortable. The large is a little snug even at the last clasp for me. Hardware is tricky cause you have to send out a whole new model and marketing stuff.
