Community verdict
Based on 15 authentic reviews, the Oster blender score comes in at 8.1 out of 10 for its inherent mason jar compatibility.

However, reviewers strongly caution that standard mason jar glass is much thinner than heavy-duty blender glass, posing a shatter risk if hard or frozen ingredients are blended at high speeds.

Oster blender bottom fits perfectly on mason jars. I sometimes prep multiple mason jars and put em in the freezer so it's a quick smoothie...
the glass osterizer blenders use the standardized mason jar mouth size so you can put the blade onto a mason jar for a "bullet" or "ninja".
If you use a mason jar - make sure all your ingredients are soft. Mason jars are much thinner glass than the glass blender pitchers.
Most people don't realize that the old-school Oster blenders actually fit standard-mouth Mason jars perfectly.
