Oster Pro 1200 Blender (BLSTMB-CBG-000)

Ice, frozen fruit and what the tests measured

Shouldit’s in-depth review, updated in 2023, gives the machine 7.3, with performance 7.1, design 7.4 and usability 7.8. Its ice test turned 12 oz of ice cubes into a very fine, sugar-like texture in 45 seconds with 0% left unblended, which the reviewer calls unmatched among the mid-priced blenders they tested. The same machine’s frozen-fruit smoothie took 5 minutes and graded chunky; a protein shake took 1 minute 49 seconds.

Plain ice, then: strong. Fibrous frozen fruit: weak. RTINGS, testing the same 48 oz glass jar with the 24 oz personal jar, rated ice crushing very good and hot blending a genuine capability, and reported Oster’s instruction to add no more than six ice cubes. Century Life got smooth green smoothies out of it, if not immediately.

Power, noise and build quality

Read 1200 W as a peak number. The only instrumented measurement found, from Century Life blending 3 cups of water, put draw at 90 W on the lowest speed, against 200 W for an Oster Versa 1400 and 85 W for a Vitamix 6300 in the same test. Idle draw was 0.5 W. Low speed is a fraction of what the badge claims.

Noise is the complaint that turns up most often. BabyGearLab reports the blender is loud at its highest setting, several owners single out noise on the higher speeds, and Century Life says the motor sounds labored at high speed. Build quality splits the testers: RTINGS says the unit does not feel very sturdy or durable, while Century Life finds it better built than most blenders in its price range.

The jar, leaks and repairs

The threaded jar bottom carries a locking lever but no marking for how far to tighten it, and one tester had the jar leak on first reassembly purely because it was not tight enough. Oster’s support desk says leakage of about 10 drops per minute at that interface is normal, and walks through the checks in order: sealing ring over the blade, tightness of the threaded cap, a cracked jar bottom, a cracked cap, a missing or degraded ring, and a load past the jar’s capacity.

Cleaning means taking the jar apart. Separate the lid, filler cap and blade and wash them before first use, remove the filler cap to vent steam when working with hot liquids, never put the jar in a microwave, and never store food or drink in it. The dishwasher takes every part except the base, and the sealing ring belongs on the bottom rack. Century Life also notes a proper clean means dismantling the jar and handling the blade.

The two parts Oster still lists are the glass jar, part 178891000000, and the food-processor bowl, part 164205001000. No exploded parts diagram or motor part number exists for this model, and the manual warns against running the blender if the locking lever is damaged or missing.

Availability, warranty and value

Start with the catch: this is a discontinued machine. Oster’s product page shows it out of stock, and Best Buy’s page for this exact model number states it is no longer available in new condition.

The warranty messaging on Oster’s own pages contradicts itself. The specification bullets advertise a 10 Year DURALAST All-Metal Drive Limited Warranty, while the warranty block on the same page says 3 Year Limited Warranty, Oster’s published warranty chart lists kitchen blenders at 3 years, and the manual for this platform carries a 3 Year Satisfaction Guarantee. HealthyAppliance, in a 2026 roundup, still repeats the 10-year drive claim. Oster’s blender warranty FAQ describes both terms for “qualifying blender models” without publishing a model list, so the defensible reading is 3 years on the appliance with a longer term on the drive. The warranty only covers units bought from Oster or an authorised seller in the US or Canada, Oster reserves the right to reject claims from unauthorised sellers, and proof of purchase is required.

Consumer Reports listed the machine at $129.99, BabyGearLab showed $130 in 2021, and Shouldit said it went for around $70 in 2023. Since neither store will sell it new today, treat any figure you find as old-stock or used pricing. Around $70 or below this was a defensible buy for someone who wants a glass jar, a removable blade, hot blending and the personal cup. At $130 or more, the measured results don’t support it.

On a used unit, the deciding parts are the jar and the drive. Check the glass for cracks and chips, since Oster’s own leak diagnostic starts there, and confirm the blade assembly seats fully and the threaded bottom tightens completely, because that is the documented reassembly failure point.

Which model this is

This page covers BLSTMB-CBG-000, the brushed-nickel Pro 1200 with the 24 oz Blend-N-Go cup, SAP # BLSTMBCBG000. The US listing is ASIN B00XHXN54K.

Don’t confuse it with its siblings: BLSTMB-CBF-000 adds a 5-cup food-processor bowl, BLSTMB-BBG-000 is the black version of the same glass-jar setup, and BLSTMB-GTF-000 is a separate model. Oster’s own page calls this machine the “Pro 1200 Plus” in its body copy.
