"A basic, glass-jar blender whose 'peak power' claim is mostly marketing."
The '700 watts of peak blending power' isn't a measure of continuous performance; it's the brief electrical surge the motor draws when starting or stalling. Real-world blending force for things like frozen fruit or fibrous greens will be significantly lower.
This is a candidate for the person who makes occasional protein shakes or simple fruit smoothies. It's for the buyer on a strict budget who values a glass jar and easy cleanup over raw power and long-term durability.
Anyone planning to make daily green smoothies with fibrous vegetables like kale, attempting to make nut butters, or crushing large quantities of ice should look elsewhere. Users seeking a durable, daily-use appliance will be better served by investing more in a machine with a higher continuous power rating.
