Susan trades in her cell phone for another model at a Bell cell phone dealer. The trade-in value of her phone is the same as the value of the other model she is getting, meaning she pays no money. Later, it turns out the new phone she just got has a weak signal because of a design flaw, and it sometimes cuts in and out of service even when she is in the middle of a city. She wants to sue Bell under the Sale of Goods Act for selling a phone not of "merchantable quality." Will she succeed? Why or why not?
