Bests & Worsts Reviews from Amazon

A friend of mine has the Acer Chromebook R11 and suggested I get it because it's cheap and he really likes it. I originally was considering more expensive options, but I had tried his Chromebook for a couple hours (writing a paper using it) and I liked it too. I ordered a new one, and upon receiving it I plugged it into the charger for its first charge. The laptop seemed to work great in general when I started changing my settings and searching for websites. However, the charger fit into the charging port very loosely, and when I moved the laptop on my lap it fell out easily. I figured I might have gotten a laptop with a faulty charging port and I returned it for a replacement. The second new Acer Chromebook R11 that Amazon sent me had a normal charging port. The charger fit well and did not fall out. But, the touchpad did not work. I tried to troubleshoot it and change touchpad settings, however every time I moved my fingers on the touch pad the cursor jumped around the screen. I ended up returning this one as well and choosing a more expensive laptop from a different company as I planned originally. My friend's Acer Chromebook R11 works fine and he has had it about 6 months. He was surprised that I had these troubles. I'm not sure what the quality control process is. It seems the experience with this laptop depends on whether one receives a fully functional one.
