I bought a Roadgear digital tire gauge at the MOA rally in Johnson City, TN.
It worked good for about a year, then the battery or something else died. It had a five year warranty.
Due to some family medical issues, I did not attempt to get it replace until a short time ago. By then I had long lost the receipt.
A reply to an email to Roadgear said sent them the non-working gauge and $5 (just like it says on the package), a receipt is not needed...they would take my word for when it was purchased.
Bottom line, I got a new replacement within a few days of them receiving my package.
Nice to see company honor it's warranty
