When a larger tank is worth the extra counter space
A bigger tank is only an advantage if you'll actually use the extra capacity. For someone cleaning a single ring or watch occasionally, a compact 180-330ml cleaner does the job with a smaller footprint and usually a lower price. A 600ml tank like this one earns its space when you're cleaning several pieces together — a full jewellery box after a house move, several family members' rings and chains, or jewellery plus a watch in the same session. The general rule: match tank size to how many items go in per cycle, not to how impressive the capacity figure looks on the box.
