How we ranked these guitar cases
Every pick ranks in Amazon's best-seller list for its category and has a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: guitar case for humidity
Watch the humidity range on the meter
A meter for a guitar case needs a humidity range that covers the dry days and the damp days, and the meters here read from 10% RH up to 90% RH or 99% RH. The Veanic 4-pack and the Meggsi 2-pack read to 99% RH, while the Veanic 2-pack reads to 90% RH. Pick the range that covers the conditions in the room where the case sits, and check the reading on the display before opening the case.
Decide whether to measure or add humidity
A meter shows the temperature and humidity in the case, and a humidifier adds humidity to the case. The Veanic 4-pack, the Veanic 2-pack and the Meggsi 2-pack are meters with a display, and the Oasis OH-6 is a humidifier with a steel clip and a syringe for distilled water. If the case runs dry in dry seasons, the humidifier is the pick that adds humidity, and a meter shows when the case needs it.
Check the battery and the pack size
Battery life decides how long a meter keeps reading in the case, so check what the pack holds before ordering. The Veanic 4-pack runs on 2 LR44 batteries with 12 to 18 months of battery life and 4 additional LR44 backup batteries in the package. The Meggsi 2-pack includes one LR44 cell battery with working time up to 10 months. A 4-pack covers more than one case, while a 2-pack covers a case and a spare.
