Dimension comparison
Power and Performance
When it comes to power, the WantJoin Professional Blender has a significant advantage with its max 1800W motor compared to the Ninja BL642's 1200W motor. This means the WantJoin can reach speeds of up to 38,000 RPM, making it capable of crushing ice and tough ingredients in seconds. The Ninja, while powerful with its Total Crushing Technology, may not match the sheer speed and efficiency of the WantJoin. Both blenders are designed for high-performance blending, but the WantJoin stands out for those who need rapid results, especially in a commercial setting.
Design and Capacity
The Ninja BL642 offers a generous 72 oz pitcher, perfect for family-sized servings, while the WantJoin comes with a 70 oz pitcher, which is still ample for both home and commercial use. The difference in capacity is minimal, but the Ninja's design allows for a maximum liquid capacity of 64 oz, which may limit usage for larger batches compared to the WantJoin. Both blenders utilize user-friendly designs, but the Ninja also includes three single-serve cups (18 oz, 24 oz, and 32 oz), enhancing its versatility for on-the-go smoothies.
Ease of Use
The Ninja BL642 features Auto-iQ Technology that simplifies the blending process, taking the guesswork out of making smoothies and other blends. It offers intelligent blending programs that adjust timing, pulsing, and blending patterns automatically. In contrast, the WantJoin Professional Blender provides 15 speed settings and a pulse function for precise texture control, making it equally user-friendly but requiring a bit more manual input. For those who prefer an automated approach, the Ninja may be the better choice.
Cleaning Convenience
Cleaning both blenders is designed to be hassle-free, but they approach it differently. The Ninja BL642's parts are BPA-free and dishwasher safe, which makes cleanup straightforward. The WantJoin offers a one-touch self-cleaning feature that requires only warm water and soap, cleaning itself in 30-60 seconds. This convenience could be a significant factor for busy households or commercial environments where time is of the essence, making the WantJoin slightly more appealing in this area.
Recipe Inspiration
The Ninja BL642 comes with a 75-recipe inspiration guide included in the package, providing users with a variety of ideas to kick-start their blending journey. This is a fantastic resource for those new to smoothie making or looking to expand their culinary repertoire. The WantJoin, while it doesn’t specify any recipe guidance, is designed with a focus on versatility in blending, allowing users to create a wide range of recipes on their own. For recipe-driven users, the Ninja offers an advantage in terms of support.
Pricing
Price is a crucial factor for many buyers. The Ninja BL642 is priced at $149.99, while the WantJoin Professional Blender is significantly more affordable at $71.10, making it about 53% cheaper. This substantial price difference can sway budget-conscious consumers or those just starting their blending journey. While the Ninja may offer more features tailored to personal blending needs, the WantJoin's lower price point could attract those looking for a reliable, high-power device without breaking the bank.
Sales Rank and Popularity
In terms of popularity, the Ninja BL642 holds a sales rank of 10,678, indicating a strong performance in the market. The WantJoin, with a sales rank of 38,812, suggests it is less popular but still a viable option for those seeking a professional-grade blender. The higher sales rank of the Ninja could reflect greater consumer confidence or satisfaction, making it a potentially safer choice for those concerned about reliability and performance.
Which should you buy?
Choosing between the Ninja BL642 and the WantJoin Professional Blender ultimately depends on your specific blending needs. If you're looking for a powerful machine with automated features, recipe guidance, and a larger pitcher for family use, the Ninja BL642 is a strong contender. However, if budget is a primary concern and you need a high-performance blender for commercial use or to serve larger groups quickly, the WantJoin offers excellent value at a significantly lower price. Consider your blending habits, the importance of automated features, and your budget to make the best choice for your kitchen.
