They're great , very close to the original when it comes to performance and a lot better than the crappy T8. they contain more gas than the oem but are prone to the leaky bottom issue and have a more pronounced cooldown effect that the original ones. they're still very satisfying eqpecially compared to the crappy T8. if you don't care about style , go marui OEM. if you do care about style , they'll do the job perfectly. one of the 6 i ordered was leaking at the bottom after a few days. the fix is simple : disassemble them and put silicone oil then grease on the bottom seal then reassemble. that did it for me and it's not leaking anymore. the bolt lock is reliable but if you're low on gas and using a stronger buffer spring or/and a heavier buffer it can fail to lock near the end of the tank. they handle 150psi well but i haven't tried with anything stronger than this.
