Buying a lot of cheap flashlights with various types of LED's is a good way for a beginner to understand the characteristics of different LED's such as Cree's XR-E, MC-E, XP-E, XP-G and XM-L or Seouls P4 and P7. etc.
However just because its made in China doesn't mean its going to be a poor quality product, there are many manufacturers that have gained a good reputation for producing quality products which are comparable to their US counterparts, such manufacturers include Fenix, 4Sevens, JetBeam, Zebralight etc.
With many things in life, you do get what you pay for, so don't be too disappointed if a sub $20 flashlight goes kaput.
