...is completely fake. The Sidewinder is a triggerless design, and fires on pump. This is quite an issue, as I'll elaborate on later.
Let's look at the drum in a bit more detail.
Here's a (poor) look down one of the barrels. Note that in place of the traditional Buzz Bee dart peg, there's a weird truncated cone structure. This piece provides a very tight seal on loaded darts - perhaps far too tight.
Finally here's the drum holders slotted on to a loaded drum.
The Sidewinder is a pump-to-fire blaster, meaning that all that is necessary to fire is to repeatedly cycle the pump grip.
Range is highly variable, dependent on your arm strength, however I have been able to get shots off at and beyond 15m. Obviously I can't guarantee them being completely flat shots, but they're definitely not on a high angle. The good seal helps greatly with ranges, if the seal were bad, ranges would probably be less than 10m.
Accuracy is as you'd expect, terrible. The push-pull firing action completely throws off any stability, and the lack of a stock isn't helpful to its cause either. Unless you risk losing power by using a more stable pump technique, it's extremely difficult to keep the Sidewinder on a particular target.
Rate of fire is thankfully rather good, as this video demonstrates:
The Sidewinder best serves a suppressive fire or scavenging role. Its high capacity allows for extended suppressive and covering fire, and its capacity is especially high when compared to non-clip/mag blasters. Though it can feel a little bit clunky to use at first, I find that it is quite reliable and so does work well for constant firing. With its exposed drum, the Sidewinder also works well for scavenging, as you can easily reload it on the move while always being ready to fire. Because of the barrel/dart cone design, it is far more difficult than usual to load darts into the Sidewinder, but again the massive capacity is a huge advantage over other blasters you might consider for scavenging.
It will take a bit of getting used to, since most blasters have a trigger and don't have such an awkward form, but in a bone stock game against non-clip/mag system users, the raw capacity and high ROF provide quite an advantage to exploit.
The Sidewinder retails for 20USD, which like most Buzz Bee blasters makes it quite a good deal. In that price range are blasters like the basic Stryfe pack (which includes barely anything) and the EAT when it was still in stock (which out of box has only 40% of the Sidewinder's capacity). While its performance is rather inconsistent, the ROF and capacity make for quite an impressive dart output. That said, the lack of a trigger and stock makes the Sidewinder far harder to control than a comparable Nerf blaster (e.g. a Rampage), and the dart cone design makes it painfully difficult to load/reload compared to most blasters. Based on how painfully difficult it is to use effectively compared to conventional blasters, I can't properly recommend the Sidewinder. I do think it has a place for clip/magless suppressive fire, but the lack of a trigger is a deal breaker.
Pros: Capacity, max ROF, can get good stock ranges with a good pump
Cons: Accuracy is hilariously poor, blaster is very difficult to keep stable, lack of stock is a big issue with pump-to-fire, can be quite inconsistent, drum is painfully difficult to load up
Rate of Fire: 4.5/5
Value for Money: 4/5
Personal Rating: 2/5 - I personally greatly dislike pump-to-fire blasters, because they're far harder to control than conventional triggered blasters. The poor barrel/dart post design also greatly irritates me.
Again, thanks to Buzz Bee for sending the Sidewinder to me for review.
