    Honestly, it's a really good purchase, totally worth the price. The material is high quality, and personally I like it because it looks perfect next to my espresso machine. It actually holds a little more than it says. 10/10, highly recommended.

    This Ninja Luxe Cafe Knock Box is the perfect companion for my espresso machine. I was hesitant about spending money on a knock box, but this one is a game-changer. The pucks fly right out, and the material is really easy to wipe clean. It's also surprisingly quiet compared to tapping my portafilter on the trash can. It looks sleek next to my coffee gear and has completely tidied up my daily cleanup. Highly recommend for performance and aesthetics!

    Concerned about longevity, price too high

    It works as a knock box. It’s not perfect at catching all stray crumbs and drips but gets most of it. It is stable and doesn’t move during use. I am seeing some dents on the knock bar after only a few weeks using it so I am concerned about longevity. The price is a bit high for what it is, with this brand and build quality I’d expect 5-10 less.

    Not just another knock box

    Pros • Mess-Free Disposal: Easily knock out espresso pucks without splashing or scattering grounds. • Non-Slip Base: Keeps the box stable during use, even on slick countertops. • Removable Knock Bar: Makes cleaning simple and hygienic. • Compact Yet Spacious: Holds up to 10 double shot pucks—ideal for multiple brews before emptying. • Premium Finish: Sleek silver design complements modern espresso machines. • Durable Build: Users praise its solid construction and long-lasting materials. Cons • Not Included with Espresso Machine: Sold separately from the Ninja Luxe Café espresso machine. • Size May Be Small for Heavy Use: Some users noted it’s best suited for home use, not high-volume brewing. • No Lid or Seal: Grounds are exposed, which may be a concern for odor or hygiene over time.

    It is a very sturdy knock box and easy to clean. It has a good appearance and blends in well just sitting on the counter next to the expresso machine.

    Yes, you could just pound the portafilter on your counter to get the groundout, but this Knock Box is really the best way to do the job. This is a very well made, solid built item to do a specific job, and it does that well. Just too bad it didn't come with the Ninja Luxe Cafe'. Very good quality!

    If you've gotten the Ninja Luxe brewing system this is an essential component. Makes cleanup after the brew amazingly quick and easy.
