16 Oz Single Serve Blender Cups for Shakes and Smoothies - Fits BL

In this review the 16 Oz Single Serve Blender Cups are judged as a practical replacement for owners of compatible BL series personal blenders who need spare or replacement cups. The bottom line: these KETAR aftermarket cups are best for people who want a convenient, dishwasher-safe single serve option and who confirm their blender model and that their original cup has four tabs before buying. They deliver the expected size and functionality for shakes and protein drinks, with an honest tradeoff between fit sensitivity and price.

Key Features

• Model compatibility: Clearly lists compatible BL series model numbers so buyers can verify fit before ordering to avoid mismatch.
• Four-tab lid design: Uses a four-tab mount which matches many single serve pro extractor lids and helps ensure a secure lock when aligned correctly.
• BPA free material: Constructed from BPA free plastic, making the cups suitable for everyday drinks and safer for food contact.
• Multi-use durability: Rated dishwasher safe, freezer safe, and microwave safe so cups can be used for prep, storage, and reheating.
• Pack contents: Sold as a two-piece set with two flip-top sip lids so users get an immediate spare or a companion cup for alternating drinks.

Who It's For

These replacement blender cups are aimed at people who already own a compatible BL series personal blender (models beginning with BL such as BL660, BL770, BL780, BL740, BL810 and similar) and need an extra or replacement 16 oz single serve cup for shakes, smoothies, and protein drinks. They are particularly useful for households that alternate beverages, prep ahead, or want a dishwasher-safe option for busy mornings.

Those who should look elsewhere include owners of blenders without single serve jars or those whose original cups use a three-tab mount; fit and seal depend on matching the correct tab count and model. Also, anyone needing an original manufacturer part rather than an aftermarket replacement should consider official branded parts.
