Don't drop it.
These work fine but I accidently dropped one on the floor and now it won't display anything. So works but they appear to be extremely delicate.

Airtight & Clean Looking
Very happy with these - seem airtight, no smell escapes & humidity is in line with my Boveda packs.Just make sure you order the correct size for your jars. Will probably swap out the battery they included with better quality, but overall really happy with these.I will buy these instead of hylids going forward - cheaper, better looking and no longer need to fiddle with their two-piece lidsFor person who dropped it - battery is probably out of place, should be fixed after adjusting it.

Not an air tight cover- seller made it right
With how much smell gets out, you might as well just leave your jar uncovered. Entire house smelled like burning man.Update: 2/26/24- seller reached out regarding my issue and resolved things promptly. Highly recommend working with them.

Work great
These work great for keeping your products in mason jars, fresh, and keeping track of the humidity. Easy to change the battery.

Doesn’t fit mason jars
This is way too small to fit on a wide mouthed mason jar.Ok I figured it out. Their default is the small one (70mm) and they only have one description that covers both sizes. So even if you read the description and believe you have the correct one Do yourself a favor and buy the big one (86mm)for mason jars.
