The TireMinder TM-88C display was updated to be more visible in direct sunlight. The photo below illustrates the newer, updated model to the left, and the original, dimmer model to the right.
Owners of original display TM-88C monitors are able to have their model exchanged at no cost to them. To do so, your item must first be registered, which you can do online here, and then reach out to us by email at info@minderresearch.com, using our contact page, or by calling direct at 772-463-6522 from 9 AM to 4:30 PM Eastern, Monday through Friday.
