Review: If Pure Volume Of Fire And/Or OVERWHELMING Force Is Your Thing....You Have Found Your Nerf Gun! - Look, I'm an old man, Ancient by Nerf standards. I had some of the very first Nerf dart shooters and I have dabbled in the hobby on and off ever since. This is the very first Nerf gun I have ever owned, that met and exceeded every single expectation I had. This thing is a bullet hose and I freekin LOVE it. I'll pro con it for you in a minute, but lets talk for a moment, just you and me.... Lately Nerf battles have begun to break out in our office. There was the odd hammershot, a Kronos or two. Before long the mega blasters arrived with their whistling foam sticks of doom. Soon things escalated to magazine fed nerf rifles, and then the flywheel blasters arrived. I contented myself for a time with two hammershots (upgraded of course). They were accurate and with the 7 round 3d printed cylinders they had plenty of power. One day I decided I was not content to come out slightly on top of the game, I wanted to scare people back into their cubes or punish them severely for daring to take a cheap shot at me. I bought a Nemesis, and I was disappointed. It's not bad, but not nearly what I expected. Then this bad boy went on sale for Black Friday, I held off as long as I could, we have a baby on the way after all. In the end I was weak and I pulled the trigger. Boy am I glad I did! This thing blows away all my expectations it is an absolute monster, and after one day on the floor NO ONE, and I mean NO ONE wants to even think about taking a shot at me. This baby absolutely BURRIES people in balls. The rate of fire is absurd, the power is outstanding, and the reactions it gets are second to none! Brass Tax Time: Pro's: Unmatched Rate of Fire (nothing else Nerf makes is even close to this rate of fire) Excellent velocity (often times rate of fire takes the place of good power, this baby has both) Holds ~275 rounds (and trust me you will need them) Includes 200 balls (Even if you go aftermarket that's 30 bucks worth of ammo, if you go Nerf it's closer to $50) Includes rechargeable battery (It's proprietary so it only works with this blaster, but still there are no batteries to buy...EVER) Looks like a monster (It's bite is every bit as bad, if not worse, than it's bark) Cons: Difficult to Aim, there is no way to aim this thing well. This is a volume of fire blaster and not a precision instrument. I have hit several innocents due to my first rounds going high and carrying a VERY long way across the office. After you let someone have it you have to go pick up HUGE amounts of spent ammunition. 8 seconds of fun means 5 minutes of gathering up your ammo. Normally I ding flywheel blasters for having to spin up, but this thing spins up nearly instantly. Blaster is hands down better than the nemesis. I would never pay the retail price of $199 for ANY Nerf blaster, that includes this one even as good as it is. I bought it on sale for $89 on black Friday and for that price it is a STEAL. My limit on a silly fun expense like this is around $100, and it's still a hell of a deal for that price. I would imagine you can get this thing for $120 and if you can I would consider that a good price on a great blaster. How much a toy blaster is worth to you, I can't say, but I'm confident once you pull the trigger you won't be able to take the smile off your face!
Review: gun started jamming and vomiting balls after 2 weeks but i was able to fix it - My kids love this toy... It was the most expensive toy I bought for them sofar... Shipping packing was just right and item arrived much faster than I thought it would. Pros does not jam shoots 200 balls fast (i think the hopper can fit 100 more, problem is where can I buy 100 nerf rival rounds?) rechargeable battery (it took 5 hours to charge though) balls shoots at a high velocity consistently without any duds Cons - a bit expensive but well worth it because the other nerf guns we bought are not as sturdy as this one and they jam a lot - looks like the balls are being skinned as they go through the flywheel as I noticed some of the balls are loosing their skin. I also noticed yellow dusts on our floor. I might need to buy new balls to replace the balls sometime in the future. After 2 weeks of daily use, the balls became 10%-15% smaller because of constant ball thread shedding everytime we shoot. The smaller balls got stuck inside both the left and right flywheel housings. The gun jams and stopped working, if both left and right flywheel housing are jammed with balls. The gun only roll out the balls off the barrel like vomiting if only one housing is jammed with a ball meaning only one flywheel is working and turning. The solutions are number 1 remove the hopper then remove the jammed balls from the flywheel housings make sure that the flywheels are loose (meaning you can turn them with your fingers freely) plus number 2 replace the worn out balls with new ones to avoid the jamming of the flywheels. I ended up buying xshot zuru chaos refills because I can't find rival rounds available in stores in my country. xshot zuru chaos balls are much sturdier and does the same thing although they are colored red which is much harder to look for.

### ⭐⭐⭐⭐⭐ How to go FULL BEAST MODE in a Nerf Battle??? Buy a Prometheus.
*by K***E on September 17, 2019*

It's that simple. This thing is a monster! You can fit almost 300 balls in this things hopper. The battery life is incredible. It comes WITH 200 balls. That alone would typically cost you fifty dollars! I own a Perses, Helios, Hades, Hera, Kronos, Chaos, Nemesis, and a bunch of nerf dart blasters. And this is my second favorite. only to the perses. The firing power of almost 300 balls is insane. It packs a punch. They sting when they hit you. Almost 8 balls a second is CRAZY awesome. And it really does deliver on all these things. The only downside to this blaster is the price. The price of the blaster itself has been remedied I feel. The msrp was $200 but now you can find it on Amazon most of the time for right around a hundred bucks. Which I feel is fair considering how many balls it comes with and what they cost. Which brings me to my other cost downside. Your reload. At almost a 300 ball capacity the reload on this thing will run you anywhere from 30 for non name knock offs to 75 for nerf brand. This isnt a big deal if you plan to play indoors. Because odds are you will find 90% of your balls when you're done. But playing outside means you're going to lose alot. Especially when you factor in that you're only way to aim is to use your line of balls blasting out of this thing. All in all it is a fantastic buy if you can get it at the right price. It is UNBELIEVABLY fun to use. Not having to reload often makes it so much less work. I highly reccomend adding one to your collection. I definitely want to buy another one
