If that catch is a deal-breaker

Highly ranked blenders whose biggest complaint is something else.

#1 in blendersVitamix Ascent X2 Professional-Grade Blender

Tom's Guide's top pick, with presets, a self-clean cycle and a 10-year warranty. It is loud and costs about $500-550, and Wirecutter has not tested this newer series.

Its catch: loud#2 in blendersVitamix 5200 Professional-Grade Blender, 64 oz

Wirecutter's long-running top pick, and the most capable all-rounder for thick smoothies, hot soup and nut butter. It is expensive, very tall and has no presets, and a sizeable share of Amazon owners report units failing.

Its catch: units failing, mixed durability reports#3 in blendersNinja BlendBOSS Personal Blender, 26 oz Tumbler

The current expert favorite personal blender (Wirecutter's top pick, Tom's Guide's budget pick) and the smoothest single-serve blender tested, but it is loud, comes with just one cup, and some owners report a leaky or hard-to-open lid.

Its catch: loud
