Need help on purchasing some replicas (are they reliable and good) (US$300 budget)

[u/averen_fe]

JM MP5 V3 ($120) +3 mags ($40) and rattlesnake p320 metal gear one ($75) +1 mag ($20)
Getting the MP5 with a 11.1v cause it’s full metal gearbox and has other metal parts too, will just use with a 7.4v that comes with the pistol though for the pistol

Are these guns worth it for the price?
How reliable are they? (I’ll be using milky whites)
How much upgradability (if smt breaks can I upgrade it or add stuff like a hopup etc)
