Choosing between a replacement knob/fader cap set and an all-in-one DJ controller might seem like comparing a spare part with a whole setup. The right choice depends on whether your current gear is mechanically sound but scuffed, or whether you need a complete tabletop controller. The knob/fader cap set is a parts-level refresh for existing mixers; the Numark iDJ3 is a full controller unit. The comparison below keeps the decision focused on condition, compatibility, and what each product actually does.
Quick verdict
If your mixer or controller still works but its knobs look worn or feel weak, the cap set is the targeted refresh. If you need a complete controller rather than spare parts, the Numark iDJ3 is the more substantial package, though the Stutter button is pushed in/recessed.

Product notes
5/10pcs Knob EQ Fader Cap Set
The main reason to pick this set is the refresh value: it arrives new, and it covers both knob caps and fader caps in mixed colors for a wide range of DJ mixers and controllers. The listed compatibility includes DJM300, 400, 700, 800, 750, 850, 900, 2000, 250, and 450, as well as DDJ, XDJ, and APC40MK2 units. The material is plastic, so the main limitation is that this is a replacement part set, not a mixer or controller. You need to already own compatible gear to make use of it, and the cap style has to match your hardware. The set is listed as 5/10 pieces, so the exact included quantity is part of the listing.
Numark iDJ3 All-In-One DJ Controller
The Numark iDJ3 is the product to consider when you need the whole unit rather than just caps. It offers a tabletop form with two decks, two channels, and a USB In connection, and it works as a MIDI controller for PC/Mac via standard software mappings. A USB cable is included. The main limitations are in the used condition: the right-side Stutter button is pushed in/recessed, and the unit shows surface scrapes and scuffs. It also has a legacy 30-pin Apple dock, so modern computer and OS compatibility is something to think about. If you accept those condition notes, the iDJ3 gives you a complete black controller with platters and faders.
Final choice by use case
- You own a compatible mixer or controller: Choose the Knob EQ Fader Cap Set at USD 12.53. It is a cap kit built to refresh worn knobs and fader caps on existing gear.
- You need a complete controller: Choose the Numark iDJ3 at USD 45.00. It is an all-in-one unit for those who want a full controller rather than a parts refresh, with its reported condition issues as the main caveat.
