    Simple, leakproof, travel mug

    I’ve been looking for a leakproof mug with a simple top because I always unscrew the lid to drink rather than flip back the sealing clip. This fits the bill perfectly. The lower plastic top has slots to allow a good but not full flow of liquid and the raised lip should reduce the chance of spillage when in a car cup holder with the lid off. Not used it yet but after two hours the contents measured hotter than my previous mug and was still too hot to drink easily. No complaints with the visual
    quality. Blue is slightly turquoise to my eyes but it still looks good.
