eufyMake E1 40oz Tumbler Ring Adapters

Not one for negative reviews BUT

I don't like to write negative reviews however none of the rings worked. It may be that the Eufy is smarter than we think. I tried with several brands and can't print on any of the 30 or 40 oz tumblers.

items delivered undamaged. Verry happy with the quality. All in all good price for a good item.

great product. tanksh
