Should you buy the Stanley IceFlow Flip Straw Tumbler (30 oz)?
The Stanley IceFlow Flip Straw Tumbler is the insulated tumbler with the killer flip-straw feature that lets you drink without removing a lid. The double-wall vacuum insulation keeps cold drinks cold for 12+ hours, the flip-straw lid provides one-handed access, the 30 oz capacity holds plenty of water, and the integrated straw is dishwasher-safe. The trade is the price (real money compared to non-Stanley alternatives) and a flip-straw mechanism that occasionally requires cleaning to operate smoothly.
