Hey, if you wanna go ahead and put a cheap Chinese PoS on your beloved old bike that you've lovingly spent hundreds/thousands of dollars on only to have it crap out some day in the middle of a ride, ruining your day/ride, and causing you a lot of headaches to either get the bike towed or go back home somehow and get your trailer and come back and drag it home to end up buying a good one so that never happens again, go ahead and save twenty bucks and get it. 'Course the cost of the tow and the hassle of all of the problems and ruining your day are gonna cost more than that, but hey, you saved some money, right?

Just having a little fun at your expense, but you get the point. In my opinion saving a couple bucks on a critical item is false economy. Whatever it is, get a GOOD one...it'll pay for itself by working right and by staying that way.
