really good leak proof 😁

This is the best overall mug I have found which meets my needs: * The wide rubber grip is well located making it easy to hold * The lid has a orifice stopper to keep heat/cold in and seems leak-proof, but I have found that depends on how tight the lid is. * I like that there is no handle, so no matter how tight the lid is, the orifice is easily available * 20 oz is a good compromise for me--not too small which would require more refills, and not too big which would be heavy to hold and sip; * Insulated for longer heat/cold retention * Small orifice for drinking means I can sip my hot beverage with less likelihood of burning my lips. * The material touching my upper lip doesn't transmit heat like its larger, clear plastic cousin, which burned my upper lip when sipping. This one doesn't. * Aluminum construction for durability * Fits in my car's cupholder. * Only two downsides: 1) I like the screw-on lid which is easy to manage. However, sometimes, it is hard to unscrew. But I have a tool for that if necessary. 2) Wish I could microwave it, but even though the instructions which come with it don't say, I assume I can't because if its aluminum construction.
