The bottom line
Here's what I'd tell a friend
What you should know first
R3 scores this 6.9/10 (Fair). The Oster Pro 1200 delivers strong blending performance (1200W, 10/10) and good usability (dishwasher-safe jar, removable blade, 3-year warranty), but the unspecified glass type drops the jar safety score from a potential 10 to 6. If Oster can confirm the glass is borosilicate, the overall score would climb to approximately 7.9/10 (Good). The lack of certifications beyond UL Listed is the other notable gap.
Go for it if...

The glass jar and stainless steel blades matter to you — these are safe food-contact materials regardless of the specific glass type
