Works great to replace a t5778 module on a homelabs 70 pint dehumidifier. Set inside a little plastic case with a snap closing lid you have to open. Started displaying the humidity and kept on working.
This is easier to transfer to another collar if your dog is a fashionista. Makes it easier for me, a senior citizen with limited hand dexterity, to detach and reattach the tag.
The claw opening is large enough get into our collars with the thickest d-rings!
Barely bigger/thicker than a hoop earring. The little locking mechanism dislodges readily. Don't waste you time or money, these bent and came open within a month.
