Lots of extras!
Size: 2+12+12+2 pack
The brushes are a bit flimsier than the original but otherwise fine. I needed it for the rectangular filters more than anything

EUFY 11S
Size: 2+8 pack
Used to replace the ones for my EUFY 11S vacuum. They fit just like the ones and got my vacuum back to cleaning really good. Didn’t realize how loud my vacuum had become until I replaced these parts.

Noice Lights from Govee!
Item Package Quantity: 2
Worth the investment especially if you have space for them and you have a big TV. I rock with a 75" in my living room. The box has a manual control module with buttons you can press, but this works with Alexa or Google Home via voice command. The Govee app unlocks way more settings and tuning, including what you see here. Super easy to set up the bars and link up everything. Easily worth the money. Brightness can be adjusted, lights are great, and color options (patterns, reactive, rotating, etc.) are fun. Cheers!
