Warranty length and noise: two things the title skips
Updated
The warranty on these seven listings runs from 1 year to 7 years. That is a wider spread than the watts. None of the listings gives a decibel figure, and owners of almost every pick are split on noise, so plan for loud.
Warranty on each listing
- Vitamix 52007 years
- Vitamix Propel 7507 years
- KitchenAid K400 (KSB4027)5 years
- Breville Fresh and Furious3 years
- Blendtec Total Blender Classic2 years
- Ninja Professional Plus BN7011 years
- nutribullet Blender Combo1 years
| Blender | Warranty on the listing | What owners report on durability |
|---|---|---|
| Vitamix 5200 | 7 year limited | Mixed reports |
| Vitamix Propel 750 | 7 year limited | Mixed. Some report failures within months |
| KitchenAid K400 (KSB4027) | 5 years | Durability is the main concern |
| Breville Fresh and Furious | 3 year limited | Some report bearing failure after two years |
| Blendtec Total Blender Classic | 2 years | Summary was mostly positive |
| Ninja Professional Plus BN701 | 1 year limited | Some report cracked pitchers within a year |
| nutribullet Blender Combo | 1 year limited | Some report a breakdown after about 14 months |
Vitamix's own product page confirms the 7 year limited warranty on the 5200. Blendtec's page confirms 2 years on the Total Blender Classic, and notes that using it commercially voids the warranty. Look at the pattern in the table: several of the owner complaints land just past the end of a 1 year term. A long warranty does not stop a failure, but it changes who deals with it.
Register it
Registering is how a maker finds you if something goes wrong. In June 2024 the CPSC reannounced and expanded a Vitamix recall of about 569,000 Ascent and Venturist series 8 oz and 20 oz blending containers and blade bases. The CPSC said the containers can separate from the blade base and expose the blades. None of the picks here are part of that recall, and the full size jars on the Vitamix 5200 and Vitamix Propel 750 are a different design. The lesson is general: register, and check cpsc.gov for your model now and then.
Noise
A blender is loud for a short time. The NIDCD, part of the National Institutes of Health, says sounds at or below 70 dBA are unlikely to cause hearing loss even after long exposure, and that long or repeated exposure at or above 85 dBA can. It lists normal conversation at 60 to 70 dBA. None of the seven listings states a decibel number, so we cannot rank them.
- The Breville Fresh and Furious listing claims quiet, efficient performance. Its owners are split, from not as noisy as expected to very loud.
- Owners are split on noise for the Vitamix 5200, Ninja Professional Plus BN701, nutribullet Blender Combo and KitchenAid K400 (KSB4027) too. Blendtec Total Blender Classic owners call it a bit loud.
- Simple fixes that cost nothing: set the blender on a folded towel or mat, keep it away from the wall and corner, and start on low. If loud sound bothers you or a child in the house, step back or leave the room for the minute it runs.
