“Nice but not perfect”

“This would be a perfect travel drink mug except the lid pops on with a rubber ring seal that is not completely secure. If you don't tip it over, it's fine. I use in the car with no problems but if you have kids or passengers who may bump it, forget it. Too bad because otherwise it's very nice looking, great size of cup holders and easy to grip when driving. Swivel top allows a small drinking hole so easy to sip coffee and keep one hand on the wheel, but the possibility of a dribble from the less-than-sturdy lid design overrides that.”
