Most AMS moisture control setups fail in a boring way: you toss desiccant inside, hope it is still doing something, and only notice a problem when loaded filament starts printing worse. That is why AMS accessories with a visible hygrometer can be more useful than another blind refill-only purchase.
Short answer: this Compatible for Bambu Lab AMS Desiccant Box Set with Hygrometer & Cable Cover(Black kit) is a smart Bambu-side upgrade for owners who want to see humidity conditions inside the AMS instead of guessing whether loose desiccant is still enough.
It is not a performance mod in the flashy sense. It is a visibility-and-maintenance buy. If your printer lives in a humid room, you keep PETG or TPU loaded for stretches, or you simply want better confidence in AMS storage conditions, this style of kit is easier to justify than generic packets alone.
What this AMS hygrometer kit actually solves
The main win is not that it magically dries filament harder. The real win is that it turns passive moisture control into something you can actually monitor. That matters because many Bambu owners are not deciding between perfect dry-room storage and chaos. They are deciding whether their loaded-spool workflow is staying under control or slowly drifting worse over time.
- Humidity visibility: you get a direct reading instead of guessing based on print symptoms later.
- Cleaner AMS moisture routine: desiccant storage feels more intentional than tossing random packets wherever they fit.
- Better loaded-spool discipline: useful when the AMS is holding filament for days instead of just between two same-day prints.
- Stronger buyer fit for moisture-sensitive materials: especially when PETG, TPU, nylon, or other humidity-sensitive spools stay loaded.
Who this makes the most sense for
- Bambu AMS owners who want a visible humidity number instead of passive hope
- people storing loaded spools in the AMS for multi-day or week-long stretches
- makers printing PETG, TPU, or other filaments where moisture drift shows up faster
- buyers who already know desiccant matters and now want better monitoring, not just more refill packs
Who should skip it
- skip it if your real problem is wet filament before it ever reaches the AMS and you need a dryer first
- skip it if you rarely leave spools loaded long enough for AMS humidity control to matter
- skip it if you only want the cheapest refill path and do not care about visible humidity tracking

Why this review matters next to cheaper AMS desiccant options
The cheaper lane is obvious: buy refill packs and move on. That still works for plenty of owners. But there is a real difference between adding drying media and adding moisture feedback. The first helps. The second helps you decide whether the first is still working.
That is why this kit fits a better buyer lane than a refill-only product when the real frustration is not just humidity itself. It is uncertainty. If you have ever wondered whether your AMS is actually staying dry enough, a hygrometer-led kit is a more honest answer.
Where it fits in the broader moisture-control workflow
This is best treated as an AMS-side management upgrade, not a complete moisture strategy by itself. If a spool is already wet, you still need a recovery step first. Then this kind of kit helps you keep loaded filament from drifting back toward the same problem.
For that reason it pairs naturally with guides about deciding between dryers, dry boxes, and storage, plus symptom-first wet-filament troubleshooting. It also has a clean internal path with the existing best AMS humidity monitor accessory guide and the lower-cost AMS desiccant refill option.
GoodPrints verdict
The Compatible for Bambu Lab AMS Desiccant Box Set with Hygrometer & Cable Cover(Black kit) makes sense when you are past the stage of asking whether moisture matters and into the stage of wanting better control over it. If you want visible AMS humidity tracking and tidier desiccant management, it is a more useful buy than another blind packet refill. If you just need the cheapest upkeep possible, stick with refill-only consumables.
