Best immersion blenders 2026-Expert reviews

I researched the best portable blenders for making smoothies at home since i am trying to eat healthier and save time in the mornings. I have been struggling with getting enough fruits and veggies into my diet because of my busy schedule. I went through reviews from trusted sources like The Spruce Eats New York Times and Consumer Reports and after comparing many options these three kept coming up as the top choices:

Cuisinart CSB Smart Speed Hand Stainless Steel Blender

Braun MultiQuick 7 3-in-1 Immersion Blender

Vitamix 5-Speed Immersion Blender

However I am having trouble deciding which one would be better for me and I would love to get your expert advice and hoping maybe some nutritionists or daily smoothie makers on this forum can also share their advice. I usually make single serve smoothies with frozen fruit and spinach so I need something compact but powerful enough to handle that. Which would you recommend for me? Any suggestions or advice would be appreciated.

Thanks in advance.
