A blender that’s anything but basic. The Oster BLSTMG-B00 features a 6-cup dishwasher safe Boroclass glass jar (thermal shock tested to withstand extreme temperature changes and safely make a frosty cold beverage right away), 8 speeds, 450-watt and the stainless steel "ice crusher" blade. The stainless steel “ice crusher” blade does just that so you get smooth frozen drinks every time.
