Novel design, one point to consider
"I've been searching for a new tumbler design that was leakproof, but still enabled sipping and was at least 16 oz - I'd say this definitely fits the bill! The colors are great, the quality seems top-notch, and I appreciate the novel design. The only reason for 4/5 stars instead of 5/5 is that while the magnetic lid fitting on the bottom is sleek, the bottom of the cup will touch every surface you rest your cup on, and that means the inside of the top does too when it's stored under the cup. Then when you put that piece back on top, it touches where you put your mouth. Not a deal breaker for me (it's good for the immune system), but just something to consider."
