Query: questions about this gun

is this gun really a cyma gun? because i bought a cyma g36 and i like it, and would like to get another gun by the same company. does the hi cap mag work well? and finally, is this gun worth the 30 bucks to buy it? if someone would either comment or write another review, and answer my questions, that would be great, thnx
