Is Oster Classic Good?
Yes, for basic blends and buyers who want glass. The linked Oster Classic has eight speeds and a 6-cup jar. Its listed motor power is 700 watts. Oster also lists a four-point steel blade and an all-metal drive. Those facts make it a sensible option for shakes, sauces, and small household batches. They do not prove that it will blend every food well. More speed labels also do not mean a smoother drink. In Oster Classic vs Ninja BL660, I see this model as the simple tool for a clear set of needs.
For a weekday shake made with milk, yogurt, and soft fruit, I would put this Oster on my shortlist. For taco night, I would use short pulses and check the salsa as I went. These are planned use cases, not reports from my own tests. The glass jar is the main draw for me. It can suit a buyer who dislikes plastic food jars. Still, glass adds weight and can break if dropped. I would choose it when the jar material matters more than cups to go or a large family pitcher.
What Makes It Stand Out / Key Features
- Six-cup glass jarThe 48-ounce jar suits modest batches and buyers who prefer glass.
- Eight-speed controlsManual settings let you adjust the blend to the food and texture you want.
- 700-watt motorThis is the listed power figure, not a measured score for blend quality.
- Four-point steel bladeThe Crush Pro 4 blade handles blending and chopping tasks.
- All-metal driveOster uses metal in the drive connection between the motor and blade.
- Dishwasher-safe removable partsFollow the care guide for the jar, lid, blade parts, and sealing ring. Keep the motor base out of water.
My Recommendation
Choose Oster if you want glass, make modest batches, and have no need to blend in a travel cup. In Oster Classic vs Ninja BL660, this is my pick for those specific needs.
| Best For | Why |
|---|---|
| Glass-jar buyers | The main blending vessel is glass. |
| Small households | The 6-cup jar suits modest batches. |
| Basic kitchen use | Manual settings cover routine blending tasks. |
Is Ninja BL660 Good?
Yes, if you want one base for large batches and single drinks. The BL660 pairs a 72-ounce plastic pitcher with two 16-ounce personal cups and to-go lids. The pitcher has a 64-ounce maximum liquid capacity, so its full listed size is not the liquid fill limit. Ninja lists 1,100 watts of power and a stacked blade for ice and frozen fruit. That broader set of vessels gives it the overall feature edge in Oster Classic vs Ninja BL660. It does not prove a measured lead in texture, speed, or noise.
For a household that wants one shake before work and a shared batch on the weekend, I would lean toward Ninja. The small cup acts like a side door: it lets you skip the large pitcher when you need just one drink. That could make a rushed morning feel less crowded. I would also favor the large pitcher for cold drinks at a backyard cookout. These are buying judgments, not firsthand anecdotes. The trade-off is more gear to store and wash. The tall, sharp blade stack also calls for care each time you remove it.
What Makes It Stand Out / Key Features
- Large main pitcherThe pitcher has a 72-ounce total size and a 64-ounce maximum liquid capacity.
- Two personal cupsThe standard set includes two 16-ounce cups with to-go lids.
- Separate cup bladeThe personal cups use a dedicated screw-on blade assembly.
- 1,100-watt motorThe listed power figure exceeds Oster’s, though watts alone do not establish blend quality.
- Stacked pitcher bladeBlades sit at several heights to work through ice and frozen ingredients.
- Manual controlsThree pitcher speeds, pulse, and a single-serve control provide direct operation.
- Dishwasher-safe removable partsClean the removable parts as directed in the manual. Wipe the motor base.
My Recommendation
Choose Ninja if you want both family batches and personal drinks. It earns my overall recommendation in Oster Classic vs Ninja BL660 through its wider range of vessels and uses.
| Best For | Why |
|---|---|
| Mixed household needs | The set supports both shared batches and single drinks. |
| Drinks to go | Personal cups come with travel lids. |
| Frozen-drink fans | The large pitcher and stacked blade target ice-based blends. |

Choose Oster if a glass jar tops your list. Its 6-cup size and manual controls suit basic blends without extra cups to store. I would base the choice on those daily needs, then compare current prices. Neither specs nor motor watts alone prove which makes the smoothest drink.
