Does The Iphone5c have problems?

Okay so I upgrade my phone in November because it's been 2 years! So at N'telos the Iphone5c is $50. I would love to get it because it comes in pink my favorite color! So I was wondering if it didn't work properly. People online have been saying bad reviews about the Iphone5C! Please let me know if you know anything because if I make the wrong descision, I'll be stuck with it for 2 years! If it does have problems, what phones would you recommend Thank you!

Get the 5s not 5c cause they 5c is made of plastic and might melt
