I received my mug last week and was able to use it the next day for my coffee...worked well, tight seal & kept it hot for a reasonable amount of time. The one thing I noticed that would make it better is if it was spill-proof, if the cup tips on its side (even with the spout closed) it will leak. I do love the look & feel of the cup; the scripture is a good reminder daily...especially with my young children underfoot!
I love the design and scripture on the travel mug but the first time I used it I heard a pop. After I finished my tea the inside lining had bulged out on one side. The water wasn't all that hot and considering the mug is for hot drinks it should have been made to withstand a cup of tea! So I was sad about that but I can still use it and it is still pretty so I wouldn't totally discount it.
I just got my grace tumbler, and I think it is wonderful. It looks great and I especially love the message of grace on it which I get to read each time I use it (which is often). Overall it is a great product and I recommend it as a gift or for yourself.
I appreciate the tumbler and I'm taking better care of it. I don't remember seeing the instructions before, but I never put it in the microwave northe dishwasher and I don't submerse it in water. If condensation build up on the outside I wipe it off and put a paper towel around it. I really enjoy it and especilly the verse about God's unfailing love.
