    I think these are very well made I know a lot of people say there not accurate I say for the money they are great you want a general info with in a few % I have one good hydrometer that that I gauge each lid and mark mason in blue tape with the + or minus so I have a close estimation of readings I highly recommend them

    Same day processing and fast shipping had them to my door in a few days. Ridiculously well-packed, it seems almost impossible for them to get damaged in shipment. Every single lid comes with a spare battery, and the hygrometer agrees with the one I own already. Just stellar service and a nice product - well worth the investment!

    I love these lids. This is a great way to monitor your product as far as temp and humidity, just a quick sure fire method.

    I have 18 of these lids and plan on purchasing more. Prior to obtaining lids it was a gamble as to humidity and when to burp product. I wasted four jars to mold and guessing. Right now using these lids I have a great way to keep an eye on my product. Thank you for them and I am looking at other options for humidifiers. I love the metal joint carrying containers, have six now and ready to order more. As a disabled veteran on limited income I have to budget for anything I need. This is money well spent!!
